The party found themselves trapped in the final cavern. Lith and Caiel sent their familiars down the tunnels; both were eaten by worms. Quickly. So were the remaining two Empire soldiers. One tunnel ahead was a dead end, while a heart-like thumping was heard in the other.
Solara failed to reach The Lady via runestone. Slate cleverly touched the runestone and extended his other arm holding a 10-ft metal rod for better reception, and it worked! The Lady told the party that the cavern ahead had a voidspan gate connecting to the Wellmet, and the worms could be drawn out of the walls by noise.
Caiel Eldritch blasted the walls, drawing out the worms - large leech-like acid-spitting worms that also can heal themselves by biting you! Battle ensued in which the Gutboy, Slate and Val dealt tons of damage, Roe clockworked their strikes, Caiel hexed everything, and Lith did some healing.
Victorious, the party rushed to the last chamber. There they saw an enormous dragon-like embryo forming the core of the moon and being fed by the leech worms. They rush through the gate to the Wellmet.
