The party arrives at Senshul to find fire giants and magma soldiers advancing on the walled keep. They are quickly dispatched and they then enter the Keep and meet Lord Sear Straybor. He has 100 able men and women to defend the keep, though the attacks have intensified over the past 2 days since Sara Missor, one of the six sorcerers from the disbanded and destroyed Hall of Thorns in Handarus. Missor is the dog wizard of fire and has portaled into the caverns below Senshal. Straybor sealed the door with stone and magic holding Missor at bay. The party may teleport/dimension door in, but none can teleport out. The party elects to go in after Missor in the morning, but hours before sunrise, great numbers of giants and elemental creatures leaving fire trails behind them, light up the horizon. A horde of fire coming to release Missor.
“Let them come,” says Straybor. “Our walls will hold. Though only long enough that you remove what calls them.”
The party, now healed and ready, dimension door into a stone passage where they see the walled up door behind them, significantly large enough for a legion of demons to pass.
