Kathros

Kathros is a small city west of Evenhold on Eamon mentioned in Wade Clarke's Cliffs of Fire. The introduction to the adventure notes that the sacred white sceptre of the high priest in Kathros was stolen by an evil renegade priest named Elrem, and that Elrem fled south from the city into the Cliffs of Fire to build a stronghold.

While the exact location of Kathros is unspecified, its proximity to the coastal cliffs and Clarke's description of it being in "west Eamon" suggest it's not far inland from the Malphigian Sea. The ability of boatmen to easily transport the adventurer between the cliffs and the Main Hall also suggests it's in the vicinity of Evenhold and likely within the kingdom.
