One of the strangest worlds in The Titan's Keys, Tizen shifts its reality between the realities of the other 4 worlds. Additionally, Tizen occasionally "interfaces" with each of these worlds and allows access to and from them through dimensional portals that allow access to "The Riverway". On its own, Tizen is a temperate world of two large continents called Kylaria and Felidon. Kylaria is well populated by a number of Kingdoms (Human, Dwarf and Elven) and territories including The Burning Coast which is also the gateway to the southern continent. Felidon is a barely populated frontier that has recently begun to be colonized by the more "expendable" members of society - mostly criminals and those who have difficulty in a more civilized setting. Reports of untold riches and insurmountable danger emanate from the wild continent that cause some to shudder and others to rush to the challenge.
