/datum/dungeon_room_themeDungeon room themes determine the style of the generated rooms. If you want to create a new dungeon generator for say, Icemeta, Then you would want to create a new subtype of room theme with maybe snow floor tiles, ice or snow walls and some fitting kind of door. Then from there further subtype into hostile, neutral, beneficial and whatever other types of rooms you want to appear in that area.
