Ruins of Kathas Castle
The Ruins of Kathas Castle lay to the east, across the river from Newhaven. The party learned of this location in Session 5 when they discovered a letter among the cultist effects:
"We flee east, to the Ruins of Kathas Castle, where the old stones are. The ritual must go on."
The cult retreated here after the party raided their previous hideout. High Order Malgora directed the relocation, and whatever ritual the cult was conducting, they intended to complete it among the ancient stones.
The party crossed the ferry east in pursuit during Session 5 and launched a failed assault on the cult compound in Session 6 โ losing their weapons and backpacks in the process.
