Tiktaq'to is a Hexoatl character. He doesn't belong to Tlaqua.
IMO, he should have been a second lord option for "Hexoatl" so that you could simply start as him or Mazda in the campaign. Not every single lord needs to have their own faction - there are in fact many that shouldn't! For instance, Volkmar and Gelt are both quite clearly associated with Franz and should frankly remain as "The Empire" and start in Reikland like Franz. The White Dwarf? Part of Dwarfs and should stay that way.
I think in that same line of thinking, Tiktaq'to should really have just been a part of Hexoatl.
Besides... Tlaqua being physically moved -- into the desert, wtf -- is just straight up silly as heck. You guys could have at least added some trees to bring the jungle up with him...
Am I the only one who feels this way?
At the very least you could have just put a made up city down there and given him a different factional name so as to not poo on Tlaqua and make one raise an eyebrow that one of Hexoatl's favorite sons is randomly attached to another major power. You did it for Kroq, after all.
