Furya

Furya is believed to be the most recent acquisition of the Dark Lords - while it's certainly a Throne World, it's only significant deviation from Earth (or any Vassal World) is that it's significantly larger than it should be - namely, it's surface area is close to twenty times that of Earth, which simply shouldn't be possible to be achieved with its Earth-like crust composition and 1.0 gravity.   It's a paradise of vibrant flora - and hell of its fauna. The foodchain of Furya is extremely - and unnaturally - long, and some of its apex predator are potent enough to be a threat to the Universal Assault Units - Dominion's tanks capable of levelling a mountain with a single round. The ecosystem adapted through evolutionary pressure alone, resulting in some truly terrifying creatures encounterable on every level of its foodchain.   Furya might be the youngest among the Throne Worlds (if you exclude the special case that Terra is), but it's also considered the deadliest. Almost everything here does consider sapients a type of food - and WILL go after you. Locals fully adapted to that, and are pretty much one more part of the foodchain, one who tends to be low on brute force - but recoups that with high intelligence and numbers.
