[GH] Sormod's Parchment

[Havard]

Sormod. a merchant-adventurer from Perrenland, came into the possession of a scrap of parchment originally recovered from Blackmoor Castle. The parchment included directions to the Rainbow Vale, and Sormod set off to explore it in Richfest of CY 453. In CY 460, a journal purporting to be that of the expedition's magician, Henriki Ardand, surfaced in the Free City of Greyhawk. This text, whose veracity has not been confirmed, describes the group's journey to the vale and the extraordinary things they encountered there.

Emphasis mine. I found the Blackmoor Castle reference interesting. Who is Sormod and who retrieved that parchment from the Castle? Furthermore, how did the parchment piece end up in the Castle in the first place?
