As the party is separated, they are confronted by the forces loyal to their foes.

Juchin, Ravel, and Teth are seriously injured as giant wolf spiders and a powerful undead attack in force—but the party is successful driving them away.  The spiders curiously vanish when slain, leading one of the party to postulate they are extraplanar, and not spiders at all.

The undead is slain, but a powerful explosion rips through the party as his lifeforce dissipates with the destruction of his phylactery.
