Trolls are definitely needed, but it would be better if they were neutral, because, in my opinion, they don't really fit into a castle. Although, in principle, it's up to you, and you can also adjust their appearance a bit :)
Here's a suggestion for the creature's name:
Creature - Horror of the Dungeons/Cave Dweller
Maybe the word "dweller" isn't the best... but I'm just sharing my thoughts :)
Great idea with the worm race! :smile54:
And yes, please hurry up with the parameters - I'm interested to see them ;)
The harpies are beautiful :)
