Pathfinder U2

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.
