A vampire master (left) and his thrall (right).
About
Vampires
Beings that subsist on human blood. They possess strength far superior to humans. Their saliva has a paralyzing effect, used during feeding. They are immortal. Weaknesses include silver bullets, silver weapons, and sunlight. They can turn a deceased creature into a thrall by introducing their own blood (pouring it into a wound, forcing them to drink, etc.).
Thralls
Beings unable to defy the vampire who turned them. They must be absolutely obedient to orders and cannot survive without their master. They must regularly ingest their master's blood. Their physical appearance may change from how they looked in life.

Guest was picked up by Theo. Race, gender, age, and other settings are free.
