Okay, you left poor Roger behind then.
Octavian and Inigo are sorting out the confusion of what just happened when the entourage comes around the corner. Octavian slaps the front of his head with an open palm.
Then BOOM, the guest house explodes in black fire. Metron multi-cast "Ball of Abysmal Flame" as he retreated through the Portal, the blackness is his exaggerated sigil. That and a remnant Taint of Evil.
The Portal is gone.
The woman is dead.
Roger crawls from the wreckage holding onto a burned and screaming child, then collapses dead.
On the bright side, the demon shows up and it is utterly ineffective. A Vessel of Iniquity, representing Horror and Despair, manifests in the road where you all are. It is a shapeless horror without definable dimension. It exhudes a power that causes panic and hysteria, but it bounces off of everyone's Parma and the grogs all make successful Brave personality rolls to resist it.
The village children are immune, because the Demon and Metron both share the same weakness in that they cannot harm children.
But the few surviving adults that remain in town, they have not acquired a might score as the children have. They go nuts.
One man and his wife had been cowering in their basement for years, and they were only just now begining to feel safe. But then he became convinced she was plotting to kill him, so he snapped her neck.
And it gets worse. But my morbid creativity is not up to the task. Use your imaginations.
