Some random info for fallen world:

It’s set on an alien planet, not an Ark, but an Ark did crash onto it and release all of its creatures.

There are lots of continents that the story will be set on: Acarb (wasteland continent), Onagob (marsh/swamp continent), Offez (mountain continent), Kysak (forest continent), Muli (snow continent) and Urun (lake continent)

Lots of creatures from the Ark evolved on this planet, but some didn’t. Here are the ones that did (not in alphabetical order):

Jerboa

Glowtail

Purlovia

Beelzebufo

Meganeura

Direwolf

Megaloceros

Megatherium

Mesopithecus

Araneo

Onyc

Quetz

Achatina

Titanomyrma

Chalicotherium

That’s it!
