Likewise, perhaps Halone really did meet Thordan and tell him where to setup Ishgard.
If this is the case, then perhaps they had other interactions with various peoples as well. For example, perhaps Azeyma travelled to Othard and ended up being the inspiration for Azim. Likewise, I wonder if the Thavnarian 'old gods' had some connection to the Twelve as well. Their prayer, which we hear during the 6.0 MSQ, sounds very similar to a particular historical figure.
