Umbra Vitae

Umbra Vitae

Umbra Vitae is a deep vampire system for RimWorld, built around a strict hierarchical caste structure ranging from mindless Ferals to godlike Vampire Kings.

Fully integrated with the Biotech DLC, the mod expands RimWorld’s xenogene framework with custom vampire genetics, rituals, bloodline mechanics, and long-term progression.

What You Can Do

• Create vampires through feeding, rituals, or resurrection.
  
• Progress vampires through 5 distinct castes: Feral, Neonate, Mature, Ancient, and King.
  
• Perform rituals to resurrect corpses, evolve vampires, or sacrifice pawns.
  
• Manage hemogen, blood purity, feeding cooldowns, and degradation.
  
• Establish bloodlines and inherit traits from the creator vampire.
  
• Sacrifice pawns of different ranks to gain permanent, stackable buffs.
  
• Control feral vampires and prevent degeneration.
  

Core Features

• 5 Vampire Castes with unique genes, abilities, and limitations.
  
• Ritual-based progression instead of instant upgrades.
  
• Permanent sacrifice rewards (Vitality, Savagery, Agility, Focus, Mystery).
  
• Custom vampire diseases, mental states, and domination mechanics.
  
• Full compatibility with vanilla Biotech xenotypes and genes.
  

⚠️ Notes

• Requires RimWorld – Biotech.
  
• Designed to coexist with most gene and vampire-related mods.
  
• Actively developed – feedback and bug reports are welcome.
