So this one took a little time to get written down, but meh. Relying on me to do it can cause that.
The party continued on from the guardian’s shrine, following the “golden star” in the sky to where it was revealed as a lingering spell above the fresh corpse of a golden great wyrm. As people approached, a ghostly apparition manifested, revealing himself as the spirit of Aroon. It turns out he wasn’t expecting this party at all (but then again, who does expect this party to show up?) but instead had sent for some other adventurers. The group managed to convince Aroonthat nobody else was coming, and that he should spill the beans.
I’m not going into a lot of details because it’s the players’ job to keep track of the details, but essentially Shearphorus has been overrun by some intruder, female with some metallic taint. The guardians are no longer behaving as they should, and Aroonhad to flee the place, but was beset by guardians and fell here, trapped in this place until the taint has been lifted from Shearphorus. He also revealed that the main entrance of the place was to fly up to the top of the 2,000ft+ spire where it’s open to the sky, but there are also some shrines throughout the bone field that were used by evil dragons to bring in sacrifices for their funeral rites. One of those shrines, the Emerald Shrine, is nearby and appears to be deserted of its proper guardians.
The group set out for the Emerald Shrine, after Gwinni cast a spell to reveal the most direct path to the center of Shearphorus. Upon approaching the hole in the hillside where the shrine is located, the group is beset by two separate forces, a group of half-dragon satyrs from the east, and a group of unknown draconic creatures from the north. The strange draconic creatures all died in spectacular fashion, four of the five dissolving into pools of acid, while the fifth literally exploded when it died. This lack of remains made any sort of further attempts at identification impossible.
