Zill O'll is a series of fantasy role-playing video games produced by Japanese game company Tecmo Koei (originally by Koei) for Sony consoles.
The games logo uses the Ouroboros which symbolizes self-reflexivity, cyclicality, re-creation, and things begining anew as soon as they end similar to the phoenix.
The world of Zill O’ll is inhabited by elves, dwarves, humans, and a vampire-like race known as Darkenith. Most are hostile or resentful of each other.
