I'm not aware ErchDragon has returned. I may have use for Ecgthow in the future, though, so I wanted to make sure everyone remembered him.
As for Marcus and Octar. Marcus was the chosen one, whose master asked him to meet Brioc and aid him in whatever quest he was undertaking. While he was traveling from Romania to Bulgaria he met Octar and was impressed with the man's character and skills. A couple days out of (insert town name)town Marcus fell ill, and the local clerics predicted he would die. Not wanting to completely fail his master, Marcus gasped out his story to Octar before falling into a coma. Octar then went on to meet Brioc and the others at the Inn of the Green Griffin. A week or so later, Marcus emerged from his coma, feeling much better, and managed to track down the others in Sevastopol.
Since this is the OOC thread, I might add that I inserted that story into their origins 1) to facilitate the addition of another player down the line, and 2) to inject a bit of mystery into Octar's origins. Whatever his motivations for continuing the adventure, they are his alone, and not based on a request from a 'father-figure.' Nor does he have any ties to the adventuring party of Brioc's father. To understand more of his motivations, one would have to ask Octar himself.
Speaking of that, Thomas Hobbes has been gone some time. Does anyone have an opinion of what we should do w/Octar? Replace him? Recruit another player? Wait? When we do reach the climax of this adventure, I don't want to be controling any of the PCs. So before then, I'll have to recruit a replacement or get rid of him in some other way, which would probably be less pleasent for Octar.
