When we first meet Dworgyn in the fallen Death School, he says that he hasn't seen any students since Malastaire left and he is surprised to learn the the school has fallen to Nightside. Merle Ambrose is surprised to learn that the Death School still exists.
Quest: The Sixth School
The school fell when Malastaire left: "When Malistaire Drake left Wizard City, he sunk the school into Nightside over his rage at his wife's death." (http://www.wizard101central.com/wiki/Location:Nightside)
This seems to imply that Dworgyn was an assistant head, already at the school, when Malastaire left and Dworgyn did not know of the school's fall.
Yet when we meet Dworgyn in the BOXES event it is before his hire at Ravenwood and after the departure of Malastaire. Dworgyn remembers Malastaire, but was not present at his departure. He is being hired as a replacement.
Quest: Carnival of Monsters
So I am confused, when Dworgyn was hired, hadn't the death school already fallen? How did he not know about its fall?
EDIT: I just did the "Meet the Professors" tour of Wysteria. When talking to Edna Fulgin, she says "I've heard of problems with Professor Malastaire, back at Ravenwood. Maybe his ASSISTANT Dworgyn will be better."
So if Dworgyn was his assistant, doesn't that imply Dworgyn was hired before Malastaire left, overlapped with him, and was NOT a replacement?
