I feel the first thing we need to determine is what it physically looks like. Like are we gonna take heavy inspiration from a monster already in fiction or try and design our own creature. Will it walk on four legs, two, eight, or none. Is it slimy, furry, or bony. I feel if we start with what we want the appearance to look like we should be able to make the rest slightly easier.

In my opinion I like the thought of a creature that travels on either four or six legs. I like the sorta monster that can crawl on the walls or ceiling. And to me a grotesque slimy creature would be an awesome start. What do y'all think?
