Create an Astrological Destiny For Your Sims

I want to share my technique for giving my newborn sims their future traits, aspirations, and careers. I give them a simple natal chart using the time, day, moon phase, and season they are born. 

While human astrological charts are complex, as they consider where all luminaries and planets were located at the time of birth and how they all interact with each other, Sims only have two celestial bodies to decide their destiny. 

 

Nevertheless, we can still build a pretty unique picture of every Sim that is born. The combinations are endless. For example, a trait may not seem compatible with an aspiration or career. But just like in real life, while some people have natural gifts, others have to work harder to overcome personality quirks to achieve their dreams. 

 

Please note that this technique works best with the Seasons pack installed. However, if you don't have Seasons, you can create mock seasons by deciding that each week is a different season in sequence and keeping a record.

 

This page shows 7-day seasons.

Sims Mary and Mordred decide to have a baby

Our happy couple, Mary and Mordred Moonstone, decided to add a new family member! Being a mystical pair, they decided to delve into the celestial realm to find out just what to expect from their little one. 

Sim Mary tells Mordred the good news, after they try for baby

After trying for a baby, Mary brings Mordred the exciting news! 

Sim Mary gives birth to her newborn

After much anxious waiting, the magical time has arrived! 

Which means that you, the Simwife observing this beautiful event, must take some special notes in Mary's maternity file: 


You make a note of the time, the day, the season, and the moon phase at the moment that the little one takes their first breath. 

When to take note of the Moon phase, Season, Date and Time of your Sim Newborn's birth so you may create a Zodiac profile

I have intentionally brightened the image of our baby's naming, so we can see the information we must note more clearly at the bottom. 

How to gather information to make a Zodiac analysis for your newborn sim

From left to right, we see:

Moon Phase: New moon
Season: Autumn/Fall
Day: Sunday
Time: 9.52 AM

Find the Sun Sign - 7 Day Seasons

How to find your Sim's Zodiac Sun Sign

Using the notes we took at Manfred's birth, we find his Sun sign by doing the following: 

​

1. In the line for the season he was born (Autumn/Fall), we check what sign the sun was in by seeing what sign falls on a Sunday at 9.52 AM. 

2. The Sun is in each sign between the times in the top row. During Autumn/Fall, in the Sims Universe, the Sun is in Libra from Sunday 12 AM - Tuesday 7.59 AM. 

3. Therefore, Manfred was born with the
Sun in Libra

Find the Rising Sign

How to find your Sim's Zodiac Rising Sign

Using the notes we took at Manfred's birth, we find his Rising sign by doing the following: 

​

1. Being born at 9.52 AM, we look to the row that shows the "time born after" 8:00 AM

2. We look across the row until we reach Manfred's sun sign of Libra and find out that
his rising sign is Scorpio

Find the Moon Sign - 8-Day Lunar Cycle

Moon Phase_page-0001_edited.jpg

Using the notes we took at Manfred's birth, we find his Moon sign by doing the following: 

​

1. Manfred was born on a New Moon, so we look along that row until we reach the column of his Sun Sign, Libra. 

2. We can see that Manfred has his
Moon in Libra.

The Simple Natal Chart

We now have a simple natal chart delineation for little Manfred!

Rising Sign: Scorpio

Sun Sign: Libra

Moon Sign: Libra

I will assume that since you are interested in giving your Sim a natal chart, you already know what the different Zodiac signs represent. As an astrologer, I intuitively glean a picture of the career, aspiration, and traits that the sim will have. This is part of my gameplay because I can't help myself.

I have, however, worked out what traits and aspirations you can give to Infants and Toddlers. I also can share what aspiration I give to child sims, based on their chart. I will do this below. These are just my interpretations - if you are an apt astrologer, you can choose whatever you like and ignore my suggestions. 

While I hope I can one day flesh out a suggestions guide to what career, aspiration and traits you can give, based on the natal chart results, for now, a good alternative is to use an AI tool like ChatGPT, as I have done for little Manfred here (for multiple options, you can use an online randomizer to pick which one): 

 

My Prompt for Manfred (you can copy this, and change the zodiac signs where appropriate):

In Sims 4, what would be an appropriate career, aspiration, and traits for a Sim with the Sun in Libra, the Moon in Libra, and a Scorpio Rising Sign?

​

ChatGPT said:

​

In The Sims 4, a Sun in Libra, Moon in Libra, and Scorpio Rising creates a complex yet harmonious Sim. Here’s a breakdown of what each placement represents and how it can be reflected in a Sim’s career, traits, and aspiration:

  • Sun in Libra: Libra Suns are diplomatic, charming, and focused on harmony, relationships, and balance. They enjoy social interactions, beauty, and fairness.

  • Moon in Libra: With both the Sun and Moon in Libra, this Sim’s emotions and inner self are also focused on maintaining harmony in relationships and aesthetics. They seek peace and avoid conflict, with a deep emotional need for balance and companionship.

  • Scorpio Rising: Scorpio Ascendants (Rising) give this Sim an intense, mysterious, and determined outer personality. While Libra is light and sociable, Scorpio Rising adds a layer of depth, making this Sim magnetic, powerful, and private, with a natural ability to influence others.
     

Best Career Options
 

Your Sim’s Libra energy makes them highly sociable and diplomatic, while the Scorpio Rising provides drive, intensity, and a desire for control. Careers that blend social interaction with the opportunity to influence others, while maintaining a level of privacy or power, would be ideal.

  1. Politician (Charity Organizer or Politician Branch): Libra’s natural diplomacy and sense of justice align perfectly with a career in politics. The Scorpio Rising gives this Sim the determination to rise to the top, whether they focus on public leadership or more behind-the-scenes influence.

  2. Lawyer (Discover University): The Libra Sun and Moon’s focus on fairness and balance make law an ideal career. The Scorpio Rising provides the edge and passion to tackle tough cases and fight for justice, especially in more secretive or high-stakes cases.

  3. Style Influencer (Trend Setter Branch): Libras love beauty, art, and aesthetics, and this career allows your Sim to combine those interests with Scorpio’s desire to subtly influence others. As a trendsetter, they could use their charisma and charm to shape the fashion world.

  4. Detective (Get to Work): The Scorpio Rising’s investigative nature pairs well with this career. While Libra’s charm can help in interviews and social situations, Scorpio’s intensity aids in solving mysteries and uncovering hidden truths.


Best Traits for This Sim


Since your Sim has a double Libra emphasis and a Scorpio Ascendant, their traits should reflect the harmony-seeking, sociable side of Libra and the secretive, determined qualities of Scorpio.

  1. Romantic: Libras are ruled by Venus and often seek beauty and love. The Romantic trait aligns with their desire for relationships, affection, and connection with others.

  2. Outgoing: The Libra Sun and Moon thrive in social situations, and this trait ensures that your Sim enjoys social interactions and builds strong relationships.

  3. Ambitious: Scorpio Rising brings a desire for success and power. The Ambitious trait will push your Sim to excel in their chosen career, striving to be the best while maintaining their Libra charm.

  4. Jealous: While Libras generally avoid conflict, Scorpio Rising can make your Sim prone to jealousy, especially in personal relationships. This trait reflects the Scorpio need for loyalty and emotional intensity.


Best Aspirations for This Sim


Libra’s focus on relationships, harmony, and beauty combined with Scorpio Rising’s desire for power and influence suggests aspirations that balance personal relationships and success.

  1. Friend of the World (Popularity): Libra’s love for socializing and making connections fits perfectly with this aspiration. This Sim will enjoy building relationships with many Sims and maintaining harmony in their social circles.

  2. Serial Romantic (Love): Libras love to love! This aspiration allows your Sim to explore multiple romantic relationships, using their charm and beauty to attract partners. Scorpio Rising adds an emotional intensity to each relationship, making it passionate and dramatic.

  3. World-Famous Celebrity (Get Famous): The combination of Libra’s love of admiration and Scorpio’s desire for power makes this aspiration fitting. Your Sim could become a famous influencer, lawyer, or politician, using their charm and ambition to rise to the top.

  4. Master Vampire (Vampires): For a more mysterious, Scorpio-themed twist, this aspiration allows your Sim to channel their Scorpio Rising’s love of power and secrecy. While this is less aligned with Libra’s need for social harmony, it taps into Scorpio’s intense desire for control and influence over others.


How to Play This Sim
 

  • Balance of Charm and Power: Your Sim will be highly sociable and diplomatic (Libra), but they may also have a secretive or controlling side due to their Scorpio Rising. They’ll thrive in careers or activities that require both social charm and influence over others.

  • Relationships Are Key: With both the Sun and Moon in Libra, relationships are central to this Sim’s happiness. Focus on developing deep, meaningful romantic and social connections, but be aware that Scorpio Rising may add possessiveness or jealousy to these interactions.

  • Success Behind the Scenes: The Scorpio Ascendant brings a desire for personal power that may not always be apparent at first. Your Sim could excel in roles that allow them to work their charm publicly (Libra) while maintaining control or influence in more subtle ways (Scorpio).


This combination creates a Sim that is both charming and intense, blending Libra’s diplomacy with Scorpio’s determination and depth.

Infant Traits

Choosing Infant Sim traits based on their Zodiac Rising Sign

Using the notes we took at Manfred's birth, because his Rising Sign is Scorpio, as an infant, his trait will be "Cautious"

Toddler Traits & Childhood Aspiration

Choosing Toddler Sim traits and Child Aspiration based on their Zodiac Rising Sign

I have used an online number randomiser on my phone to work out Manfred's toddler trait.

 

Because he is Scorpio Rising, as a toddler, he will be "Clingy".

Likewise, using an online number randomiser when Manfred is a child he will have a
"Mental" aspiration.


 

Optional: High School Years Aspirations

Choosing Teen Sim aspirations based on their Zodiac Rising Sign

I don't always like giving a specific teen aspiration, but I know some Simmers do.

So this table shows what you can allocate to a Teen sim during adolescence. 

So, using Manfred as an example, his teen aspiration would be
"Goal Oriented".

 

The Simple Natal Chart's Delination

Using the information I have gathered above (and a handy number randomiser), I can now build a picture of Manfred's personality and future:

 

Infant: Cautious
Toddler: Clingy
Child: Mental Aspiration
Childhood Trait: Outgoing

Teen Aspiration: Goal Oriented
Teen Trait: Jealous
Young Adult Aspiration: World Famous Celebrity
Young Adult Trait: Ambitious
Career: Politician (Charity branch)

 

 

This is all just for fun; I hope you enjoy it!
