After destroying its Devil guardians, the group loot Kazavon's Throne Tower of much loot and retire to the Orc-Held Outer Bastion to rest. Laori Vaus discovers that by wearing a golden circlet looted from the hoard she can see through the eyes of Castothrane, a Skeleton Warrior and Soul Anchor who guards the Gatehouse's battlements accompanied by two more skeleton fighters.
30/12/4708.
The group make an air assault on Castothrane and his 'men', facing only moderate resistance as Kaz's ankylosauri crush the undead champion into the wall, and Megrim finishes him. With Castothrane's demise his soul is released to whatever hell awaits him. The Dimensional Anchor over Scarwall fades for a moment, and hundreds of souls escape into the morning sky (including a powerful Dread Wraith), though thousands more doubtless remain trapped within the walls as the Anchor swiftly returns.
Next they proceed to Kazavon's ballroom at the west end of the castle, save Laori Vaus from an unfortunate incident with a cursed statue of Kazavon, subdue the Danse Macabre in the dance hall, and loot the corpse of a tortured knight buried beneath the ballroom floor. They locate the secret door by which Mandraivus' band entered Scarwall, and collect the platinum coin he dropped there for luck more than 600 years ago - it could be worth 200gp to the right collector!
Finally the group decide to assault the Donjon, where resides the Temple of Zon-Kuthon, Unholy of Unholies. Getting in and out proves problematic, twin powerful Forbbidance rituals shield the place, but the half-orc Shaman manages to Dispel the ward against entry by the non-evil. Laori is blasted by the Forbiddance that bars exit to the non-good. After ritually cutting and cleansing herself in the anteroom, she curls up by the pool for a nice sleep.
