After having successfully delved into the depths of the Shrine of Pelor, the party was given an orb fragment which is currently held by Marilena. This fragment is one of four pieces that make up the Orb of Pelor.
Pelor has tasked the party with making his orb whole again, and to return to the shrine when they have finished. The only information he has given them is that the remaining 3 pieces are representative aspects of fire, water, and earth.
Recently, it's been discovered that the fire fragment sits atop a scepter that belongs to the Lord Mayor of the Firetip Caverns. It's the hereditary symbol of power in the FTC and suspected payment for the The Great Betrayal of old.
