I've just finished recreating ESO fish when High Isle expansion dropped. Oh well, it's just a few more fish, and nothing seems to be poisonous, venomous, or infused with Hist sap.
Other than that, and before I shift focus to another mod, I want to make all the creatures from Gregory Keyes novels. These, however, raise a question:
What the hell is a greem? Apparently they are something worth seeing, they live in flocks, and can be encountered in Elsweyr, so I imagine they are like fancy dodos. My first idea was to make them into quadrupedal ibises, but that wasn't really consistent with ES aesthetics. Elsweyr has glyptodonts and terror birds, Skyrim has mammoths and sabre cats, so a dodo is not too strange.
What comes later? I'm considering continuing the Jurassic World dino hybrid mod, Slay the Spire mod, or the Ravenloft thing I started a while ago and pretty much abandoned (something happened to the ectoplasm material, no idea what though) .
There's also the Miscmod (that could really use a new name). Once I get back to it, I'll merge it with the old Cavern Fauna mod. There are also demons that I started and never finished, and the Wukong monkey civilization.
Now, I promised myself not to start any more projects, but I have a plan to make a Might and Magic mod, mainly centered around games set in Ashan (Heroes V and later), because the setting has more consistent factions and dwarves as their own civiliaztion.
The civs would be: humans (including angels and celestials), wizards (humans, gremlins and genies), necromancers (humans, liches, vampires, fate spinners), elves (and sprites), dark elves (maybe even faceless?), nagas (plus wanizame?), dwarves, orcs (various castes, including goblins), demons (many castes).
There would be heroes as secrets, also somehow attainable in dwarf mode, and also the dark messiah - a necromancer variant capable of summoning the Avatar of Death.
It's still just a concept, of course, and it will likely stay that way for a while.
