Deadman's Party

After resting the night just outside the dead city of Erdina.
The party awakes to find Bael and Melkior gone (Bael was last to be on watch). They did a quick search and found no sign of them. They didn't have much time to mourn the lost, because shortly after this discovery, they spotted a party from Erdina with dogs and torches. After a brief attempt at hiding they were spotted by the group, and then agreed to follow them to the keep (Rhodri remained unseen following the group).
They had an uncomfortable evening with the group of gothic individuals and their toadying servants. They learned that the villagers of Green Meadow were in fact in the castle, being tended to in the makeshift hospital. Khord tried to help the people but found himself unable to help them much. A casual inspection of the home reveals some secret halls and other odd facts. The next day they left the area and discovered from the mind of the gatekeeper that the leaders of the keep were in fact undead. They decided after seeing the porters safely out of the city to gave it one last search by Astral Travel reveal both the presence of ghoulish incorporeal undead and Bael and Melkior unconscious in the catacombs.
They traveled once again to the keep and found some kind of party in the making. Dodging the party they went to their room and quickly headed for the catacombs. After Rhodri made quick work of the massive doors they encountered the angry giant Dru Alurin in full battle gear, a suit of plate mail with a death mask helm, and viscious looking scythe. Rhodri used a Hero point to stun the giant with a throat gouge. They succeeding in felling the dark champion in relatively short order. This gave they mission even greater urgency, it was unlikely they could plead innocence with their dark hosts now. A brief search afterward reveal more of the maze like structure including one room with a normal looking cat. The cat immediately attacked and scratched Rhodri before Rhodri killed the cat. They searched the maze further, and found the spot where Bael and Melkior were resting. Their friends were gone however. The party feared the worst, that their trusted companions were being used in some hideous ceremony. They raced to save their teammates but as they left they heard the sounds of yet another cat. Can they survive the might of yet another kitty?
