Cavern Set (Item Set)/Notes

This Collective set contains 15 distinct sets, making this possibly the largest super-set in the game.
Each Type of Armor (Int Cloth, Wis Cloth, Leather, Chain, and Plate) has a simple set, a PvE set, and a PvP set.
We have no idea where these drop. The RoM-Welten database does not list any Treasure Table or Enemy drop information. It is highly possible this set is considered OP and was removed from the game.
