Sorry I didn't have all of this in my initial posting, I'm new to the process and like a dunce I didn't read the sticky until after the fact.

Molon T`plth should be on there too - he even used to have a script where he would walk from the Hall of the Ebon Mask to Maiden Fancy (where he stays now) and have a dialogue with Ratraz the troll, who would deny him entry.
