Crypt of the Silverblade Triplets

Open archway (east), doorway (door missing, west). Three sarcophagi pointed north and runnest east to west. Pool of water in room. The Blackwater goblin clan had heard about the dark magics surrounding the Silverblade triplets (Ashem, Gira, and Bellim) and avoided any desecration of this room... and for good reason. The triplets were not favored among the Silverblade family, but the family would take no chances in upsetting their possible spirits and placed them in the family tomb after their deaths. The triplets' attempt to become liches had failed, thankfully, but their surviving children made certain to hire the best sorcerers to seal and ward the sarchopagi in this room to prevent them from ever being opened. Unknown to the triplet's children, one sorcerer chose to incorrectly ward the sarcophagus of Ashem, the most powerful of the triplets. The sorcerer intended to return one day and negotiate with the spirit of Ashem in order to learn from him. This never happened, and the ghost of Ashem has been trapped and waiting for centuries inside the sarcophagus. Each of the sarchopagi are protected by a magical ward. The ward will glow brightly when any living creature moves within 5' of a sarcophagus. Should the lids of either Gira or Bellim be pried open, all within Area 3 must save-versus-spells or take 1d8 damage. All sarcophagi are empty except for bone fragments. Ashem's ward, however, fails and requires no save. Instead, it will release Ashem (chaotic ghost). Ashem will attempt to possess what he perceives as the most powerful magic-user first. If no magic-user is present, Ashem will attempt to possess a cleric in a similar manner. If possession of a magic-user or cleric is not possible, Ashem will attack the PCs for 1d4 rounds before fleeing and hiding in a pool of water in Area 1. Ashem will remain here until the PCs return to Area 1 where he will attempt possession of a random PC in order to leave the tomb. If Ashem is able to possess a PC, it will attempt to communicate to determine how long it has been since he died. (PCs are unlikely to know this information.) Ashem will only agree to voluntarily leave the possessed PC if he is escorted out of the tomb. If this happens, the ghost will dispossess the PC and flee without incident.
