Urth

[Enkidoh]

Yeah, I'm pretty sure an earlier quest also mentioned Urth was a sorceress who was the one responsible for sealing Odin - I just can't remember where it was exactly. I'll have a look through my screenshots and see if this is correct.

EDIT: well, I found the relevant screenshots, but the dialogue is rather vague - it mentions that Urth was slain by Odin, but as to who actually sealed him is unknown, other than a 'great hero of the Allagan'. So we're back to square one (no pun intended):

O-App-Pesi: "Odin, as the ancient writings have it, rode forth into our world, wielding a dark blade capable of cleaving earth and the heavens. By his fell blade did perish Urth herself, and countless multitudes of her people."
O-App-Pesi: "At long a great hero of the Allag did arise to do battle with the dark god. Odin was slain, and his spirit sealed within a forest spring."

So, is Urth the actual 'hero of the Allag' mentioned, and that the order of events has simply gotten jumbled over time? Or was someone else responsible? O-App never mentions exactly who it was who did this, and given the fact that the whole story until recent times was regarded by many in Gridania as nothing but a myth, it does make the 'record of events altered over time' idea more logical, especially during that questline after returning to the Waking Sands and speaking to Urianger, he has this cryptic dialogue:

Urianger: "Whilst you were afield, I immersed myself in the ancient scriptures. The more I scoured the words, the more I did realize that the writings draw heavily from ancient Allagan historical chronicles."
Urianger: "History is quite a fascinating beast, is it not? One nation's glory is another's suffering - one nation's great hero, another's most abhorrent villain."
Urianger: "I mean not to speak in platitudes, only to say that there is never but a single side to every story - even a story that is presented as historical fact."
Urianger: "To what end did the great hero of Allag seal Odin in a gaol of crystal? What impels the Dark Divinity to ride once again? Cast thine light on the shadows of history, friend, that we might be delivered from the darkness."
