Nah, the wiki article is fine for what it's meant to be. Particularly when you consider the nature of some of his avatars, Lorkhan as a "trickster deity" fits well, if you understand what is meant by the term "trickster deity" and its meaning in the study of mythology. I simply object to referencing a wiki article as "proof" in a lore argument... particularly one that is being played as containing heavy doses of ethnic bias. The UESP does not exist in-game OR in-universe by any standard.
It doesn't make the info totally unreliable it uses in-game sources for this stuff correct? Also, its the devs who stated non-ingame sources aren't trust worthy but in-game sources from only Oblivion are
very questionable due to how little lore Oblivion followed from previous games so I wouldn't say the devs are right on this. If we come across a reliable out of game source its just fie to use it when talking about the lore. Some information that is clearly opinion shouldn't be trusted but the stuff on Lorkhan seems more fact then opinion.
