I think it makes a difference, if you are writing about a corpse (thanks for pointing out that mistake) from a person of an organization that is around the Sword Coast for a long time and has a lot of lore, or about a person that has the same name.
Trust me we don't need this level of precision here. To make sure that Larian can find what I'm talking about I'm taking names of objects right from the game, aside from the corpse of course, because he's just "corpse" in the game, so I wrote "supposedly Harper's corpse".
