I like the Skritt too :)

I would love for some in-game group (maybe the inquest) to just do an experiment and try and ramp up the Skritt intelligence as high as they can go.

I also really like the ideas of the mists and how everything seems to have come from the mists, but also everything that forms then impacts the mists kind of like rebounding echoes of reality.

I always enjoy my modded Skyrim playthroughs as a vampire.

There are tons of vampire related mods.

I use the Better Vampires mod as my main, to really tweak how the vampire experience will play.

I have also been using the Vampire Lords Can Fly mod in my last few playthroughs and it’s a lot of fun.

The Dawnguard DLC has a whole Vampire related quest line and there are mods to get even more vampire specific content.

Combined Solution

Changelings (d&d style), Doppelgangers, Werewolves, really any kind of shapeshifter, the more shapes/types they can take on the better.
