Here is a little list of the OCs in DD, in case you’re trying to keep track of who’s who. I think I’ve caught all of them. Drop me a note if there’s someone you think I’ve missed.
*Some of the character descriptions contain minor spoilers if you haven’t read the entire story.*

Resolving a Misunderstanding, Death’s Dominion, “Now is Perfect,” and “The Unsentimental Arithmancer” are all available on fanfiction.net, and A Holiday with the Headmaster is available in a T-rated version titled A Little Holiday.
Death’s Dominion has a new OC Muggle Studies teacher, Amanda Teller, because I can only associate the canon character with the single, disturbing scene in which she appears in DH. I admit it: I’m a wimp with a sensitive stomach. In DD, the other witch is happily growing prize-winning roses and degnoming her gardens!
Kevin Harper, the fifth-year Slytherin who appears several times during the Hogwarts Battle chapter, is not precisely an original character, although we only have his last name in canon and no description of him other than that he is a Slytherin. There are a few other very peripheral DD characters whose names come from canon but about whom we know very little. Ritchie Connolly is another of those whose last names I took from canon, but I gave him his first name; he’s a Beater for the Irish national Quidditch team.
