PCs settle into Highmoon, find the Naibot School there, and give the scroll to Nantole, an elder scholar of the school, who will try and deactivate the self-destruct ward on the scroll so it may be opened and read.
Magnus and Thanatos bed Higla and Re-enna, respectively. They are local miners who are regulars at the Highmoon Pub.
The PCs respond to a general call to arms, meet with town elder Cadrick, who asks them to evacuate the brothers at the Monastery of the Sundered Chain because there has been sightings of invading orcs in the mountains.
When the PCs arrive at the monastery, they discover that it has been ransacked, defiled, and the occupants put to the blade. The PCs systematically kill all the orcs in the monastery and rescue two prisoners of the orcs: Kerrang the Githyanki, and Kalad the Dwarven smith.
Kalad alerts the party to the possibility that the orcs have found the Nexus, which is a crossroads under the mountains, under Bordrin’s Watch, that will give the orcs passage through the mountains and into the Dalelands. He guides the PCs to the vents that lead to the Nexus, and more orc slaughter ensues.
