@broozar: thanks, that did it!

@EX Citer: well it's like D&D! Somehow you get in a Dungeon, slay the monsters, get there money and leave. But I'll try to get a nice but simple story.
What about: you are an elf, striding the woods, get to a dungeon, the earth collapses and can't get out. you have to find another exit.

@Zeitwerk:
Yes they fit so good to my game! I really love these textures!
