Feargus Jewhart
Savant
She left a year before DA:I came out. People love to hate on her, but she's actually responsible for a lot of DA:O's dark fantasy feel.
Codexers will never admit Hamburger Hepler is actually a really good writer as long as she has someone to slap her when she's about to write fujo shit. She's responsible for almost all of the dwarven lore and some of the best quests in DA:O. She wrote the dwarf commoner quests and most of the paragon of her kind. That's why she was made into the lead, because she excelled in DA:O. She was also responsible for overseering design of all the plot and quests in DA:O.
Too bad she's a fujo into degen stuff that needs a tard wrangler and didn't have someone to slap some sense into her during DA:II.
