Faerie Caverns

Cut off from the traditional annual seasons, subterranean fey tend to be less devoted to the Great Cycle, more often straying into interest in the complete preservation or extinction of things. As a result, the Harbingers of the Undying Season tend to carry out their life- and death defying operations more freely in these places. Similarly, the members of the frigne Seelie House of Worms are at greater liberty to experiment with the potential of aberrations to be remade into forms compatible with the natural order.

Also prominent in caverns are the Fomorians, who often influence the fey with their strange fixations and magic. Their strongholds make use of the dark secrets often hidden beneath the earth to carve out great realms guarded by fortresses of iron and eldritch wards.
