So that explains why Talos doesn't appear in TES I + II.... but that would mean that Zurin Arctus is Talos, not Septim..... So how works that?
"B-b-but Arctus was killed by the Underking after after an ambush set up by Talos to kill Wulfharth....
"Wait...but Wulfharth is the Underking...so why the [censored] was he saying he's Arctus in Daggerfall???
"And wasn't Wulfharth responsible for conquering Skyrim and High Rock while Talos was working elsewhere, like the Arcturian Heresy states? ...But wasn't Talos the one who led the armies that conquered those provinces??? Talos COULDN'T have been in more than one place...could he?
"And what the [censored] is http://www.imperial-library.info/interviews/vivec.shtml??? Vivec killed Talos at Red Mountain!? No he didn't! http://www.imperial-library.info/mwbooks/wulfharthsongs.shtml!! Talos wasn't born yet! How did he kill him???"
....You see what I'm trying to say here?
