I concede defeat.

You encountered a wild Odin.
Go Thal Icebound!
Odin uses Error 90000. It's super effective.
Thal Icebound is inflicted with Error 1017.

The server crashed once too many people showed up in the south Shroud.
But, some investigations were in order. (Kudos to Rogue Muse and Gold Lion.)

The L53 Odin had an ownership name in this iteration:
<<Kennard Drakeheart>>
We found his lodestone profile here.

And this is what Odin Looked like.



The faces align perfectly. Odin's appearance seems to be linked to character interaction in some form or other.

Meaning he isn't Louisoix. ;_;
