For Drem and Demented characters from the Forbidden Cults DLC who start with The Worm That Devours quest but go to complete another starter zone to level up before entering the worm; when you complete the quest and receive your racial starter quest, the completed zones will be applied retroactively, if applicable. (For instance, if you complete Trollmire and then return and kill the worm, and if your next quest is "Of trolls and damp caves", it will reflect that Prox has already been killed.)
