Castalia is a futa Unicorn that works at the Library in Town.

Overview[ | ]

Like most other Town NPCs, Castalia has a few unique aspects to her.
First is her genetic trait Royal, which increase her brothel value by 25%, making her invaluable when setting up units for the Brothel. While Evolution and Creation can just copy her trait and give it to others units, Druid has to set up a Breeding program.

As with the rest of the Town NPCs, Main Character can learn an unique skill once their relations with Castalia hit 100, which is used exclusively when both are in battle. Castalia's unique skill is LustBurst, it removes all Lust from Castalia and deals damage equal to half of that amount to all neighbouring units.

Combat[ | ]

Castalia is a support unit that is very similar to a normal Unicorn but with access to FullHeal and Protect, and she has the Mana growth to use them, insuring that your team is always in top form.

She has an unique passive LastingMagic, that gives Empower to units that she fucks for the rest of the combat, making her a great support unit for magic heavy teams.

Relationship[ | ]

The following actions raise her relations with the MC.

  • Submitting new species to the library bestiary (+5 relations, no cap, lose the character)
  • Offering her a character with Mana gene 5+ and the Intelligent trait. (+5 relations, no cap, lose the character and gain level-based gold)
  • Reading at the library while she's present (+1 relations up to 30, +2 Stamina, chance of +5 exp, takes 30 minutes)
  • Bathing with her at the River (+2 relations, not cap, +3 Stamina, takes 30 minutes)
  • Sleeping with her in her room (Requires 20 or more relations to unlock. +3 relations, no cap, +40 Stamina, gain Cock sex skill, takes 6 hours)
  • Gifting her 100 gold (+6 Relation up to 30, then +2 relations, caps at 50, -100 Gold)
  • Setting one of your units as a Helper (chance of daily +2-6 relations, no cap)
  • Date (Requires 20 or more relations to unlock. Relations and Lewdity received change based on choices you make)

Wife[ | ]

Marrying Castalia will remove all time and stamina costs of crafting and give you a random concentrated potion each day.

After becoming your wife she can learn the following skills:

Events[ | ]

  • When you first enter the Arena during the first days of a new game, she can be found arguing with Aila about whether strength or intelligence is better. Choosing intelligence will increase her relations with you by +10, while choosing strength will decrease her relations with you by -10.
  • Once a day and as long as your relationship with Castalia is at 21 or above, you can trigger one of two events with her in the Research Room.
    • The first one is helping her milk centaur cocks, it takes 1 hour and you gain exp in Hand and Mouth sex skills, and if you're playing Evolution or Creation you also unlock random types of centaur based species.
    • The second one is drinking a mysterious vial and receiving a blowjob from Castalia, it takes 30 minutes and this will either increase your cock size or your cum amount permanently.

Notes[ | ]

  • Castalia has the most dynamic schedule of all the Town NPCs, working in the Library between 7:00 and 18:00, doing research in the Research Room between 18:00 and 22:00, sleeping in her Room between 23:00 and 5:00, and taking baths in the River between 6:00 and 7:00.
  • Castalia is the only Unicorn without Charge movement.
  • When you start a new game with the Partner trait, you must make sure to recruit her before triggering the event in the Arena, which can cause her relations with you to go lower than required to recruit her.
Sex Skills

She starts with Bad in all her sexual skills, and can get up to God in all skills.
