Pathfinder U2

The heroes spent a couple of hours looking for the lich's phylactery in the crypts. In the northwestern corner of the assembly room is a hidden trap door that the heroes discovered — it opens through the roof of the area containing the lich's phylactery , the floor of which is 10 feet below. Aranthor joined the heroes around that time, after he was shunted to the Material Plane from the lich's spell. Phylactery.  This crypt contained three stone sarcophagi, each bearing detailed carvings of hundreds of capering skeletons and dancing corpses. These three sarcophagi were protected by a dangerous trap. When Gryxxa tried to open one of these three stone coffins, the skeletons and corpses carved on the sides of all three suddenly animated and began shrieking in a bloodcurdling manner. Hundreds of little bony arms pointed out into the room, and from their hundreds of outstretched fingers sprang beams of necromantic fury. One of the sarcophagi contained 11 spellbooks. Each of thes...

The lich kept casting spells like fly and mirror image while separated from the heroes. After the heroes joined him past the wall of force, he dismissed it and started casting offensive spells. One of those spells made Aranthor disappear. The remaining of the heroes eventually destroyed him, but they have yet to find his phylactery.

The heroes defeated the omox demon and managed to rest. They then went into the cold chamber with the black energy to shatter one of the crystal pylons. When they destroyed it, it exploded. Once it was destroyed, the black energy vanished. When the rippling curtain of blackness was destroyed, it yawned open for a brief moment allowing a powerful monster to manifest in this chamber. This creature looked like an immense bat made of roiling blackness with two glowing red eyes. The creature was furious and immediately attacked the heroes. This room’s dimensions didn't allow the creature a large amount of mobility. It focused its wrath on Zemurin. The creature fought until destroyed. The heroes then went after the lich, who was again guarded by a devourer. The lich opened the battle by casting finger of death  at Aranthor and more spells on himself. He then sealed himself off from the heroes, giving him time to cast more spells. During this time, he let the devourer keep the heroes busy...

Arkrhyst eventually escaped the heroes when the battle started to turn against him. Exhausted, the heroes tried to rest, but an omox demon interrupted them. They are still fighting this battle.

The heroes managed to slay the troll, but are still fighting the dragon.

The heroes returned to the crypts after recuperating and preparing in Korvosa. There they encountered the white dragon whose hoard they stole, aided by a troll.
