As the party reached the bottom floor and searched the cellar, they discovered a hidden door behind a bookcase. This door led to a passage that branched off in two directions: east and west.
In the west chamber, the party found a large room with stone caskets lined up against the walls, illuminated by a faint blue glow similar to the one given off by the crystal upstairs. The party cast a fireball spell, destroying everything in the room.
In the east chamber, the party encountered Orion in the midst of an incantation, protected by a Zombie Beholder. After defeating Orion and his minions, they discovered Echo, also known as Lyndon, a member of Blackwing they had been searching for.
The party learned that Blackwing had been hired by someone else to investigate Vespasian, the leader of the Order of Lotus. They were instructed to either travel to Candlekeep or seek out Hadrian Blackwing, the founder of Lyndon’s order.
