Arctic lake biome

Cire555

I was looking at some of the concept art (specifically the one with the giant sea worm thing) and I was thinking a land locked arctic lake biome with a few unique species and maybe a giant eel-like leviathan (like in the concept art) trapped in the lake wear from the general ocean would be a pretty fun idea. They could place it in or next to the arctic spires biome and situate an almanac cash underneath to create a sort of “boss battle” scenario which would provide an opportunity for a few cool creature based cinematics. Just an idea, what do you guys think?
