Is it rude to summon Demi-Bahamut?
Tiamat bound herself for centuries as punishment for summoning the primal Bahamut, which she saw as desecrating the memory of her love, the true Bahamut. It seems like when Summoners use Allagan techniques to summon Dem-Bahamut — a subservient simulacra of Bahamut — there's a solid chance that Tiamat would find this to be similarly abhorrent. Given this context, it seems like summoning Demi-Bahamut would at the very least be a faux pas.
I'm curious to hear the thoughts of my fellow Warriors of Light on this matter!
