Crios features slick, cinematic game mechanics based on the acclaimed Renaissance D100 system, and is compatible with other D100 system games.
Crios is a tabletop role-playing game of a world at war. Together with a group of friends, you take on the role of soldiers, spies, wielders of arcane magic and specialty priests. You can be an Elf, Dwarf, Goblin, Halfling, Human or maybe come from a line where there is a dragon secretly in your bloodline.
