Okay, so, I was looking at both this wiki and the UESPwiki for information on the Mages Guild, and I came across a bit of a dilemma: this wiki says the guild was dismantled during or after the Great War, but UESP says it was after the Oblivion Crisis. The UESP cites the Elder Scrolls novels, The Infernal City and Lord of Souls as proof, but I haven't read them and I don't know if they can be considered canon (read somewhere that nothing is canon in the TES universe, and a lot of people supported that claim--but please correct me if I'm wrong). So my question is, was it after the Great War or the Oblivion Crisis? Apologies in advance if this question is comes off as really stupid; I'm not very well-versed in the lore and I'm very confused right now.
