Lord Adoril Serpenthelm, said to be one of the Gatekeepers, guarding/keeping closed a portal between your realm (the planar realm) and another, otherworldly, realm.
The cloaked old man from Haven who gave you your first quest of the campaign.
A militia guard in Haven told you he seemed like a nice retired old man who used to be a scribe/cartographer in the capital.
Adoril was the one who tasked the party with retrieving his maps and family jewelry/heirlooms.
You got the impression his jewelry wasn’t in his family for hundreds of years like he implied…
When the party returned to Haven after retrieving the items, they found the city ablaze and Adoril dead in his home with three drow dead beside him. Clearly there was a major magical fight, and the drow were looking for something…
