What's your canon ending?

First time I played Origins I romanced Alistair, so the dark ritual was also my first ending
I've since also done a playthrough where Loghain performed the ritual, and also a playthrough where he was sacrificed to the Archdemon
I've never really done an ultimate sacrifice ending, or one where I sacrificed Alistair and I don't think I plan on doing them.

So yeah...dark ritual performed by Alistair is my canon ending

Most of the time i play a female warden and choose the Dark Ritual with Alistair.
But i had one playthrough with a male warden that romanced Morrigan and performed the Dark Ritual with her, another one with a male warden where Loghain performed the Dark Ritual, one with a female warden where Loghain sacrificed himself and one where my female warden did the ultimate sacrifice (with this warden i had Alistair sacrifice himself just for the achievement but i reload the game and made her do the ultimate sacrifice instead).
