It should contain a mix of Rock, Steel, Ground, and Flying-type Pokemon. Feels like a cave, but has fliers to reference Galarian Articuno. Could change some stuff out for more Psychic-types given Galarian Articuno lives there. Needs more level distribution - namely, buffing near the end a la other caves.
Currently just uses the RG Unknown Dungeon map, which should be changed accordingly. The warps and stuff outside of basic entry aren't implemented.
Has a halved encounter rate compared to other maps, which matches the idea that caverns don't sustain much wildlife.
Mt Moon theme may not be used in the final product.
