The Dark Arcane theme has mismatched textures: the runes along the walls and the edge of the dungeon core do not match the glow texture, as though the two are in two different alphabets altogether. This is because the Dark Arcane theme uses the game glowing texture as the regular empire Arcane theme, which does match its texture.
