The group passes into the darkened portal.

Sure enough, as Walter was warned, once past the portal the light from his crystals or from Reiko's sunrod only extends 5' before abruptly stopping instead of dimming out. This doesn't mean that you can't see the other light if you separated ... it just means that the overall pool of light is extremely small.

Half-melted blocks o f green glass lie thick on the floor. A crumbling archway to the north leads into another chamber, while a door to the west leads into the round tower at the southwest corner of the building. To the east, a barricade of rubble and wooden stakes blocks a passage leading into the tower.

This is actually the first time the returnees have had enough of a breath to be able to get a sense of their surroundings.

What now?
