The Emperor (A Dragonsong Spoiler)

[Felis]

maybe he will actually assist the warrior of light with a decent airship to defeat Bismark (eorzean ones are barely fit for combat at this stage)? while he will obviously try to conquer eorzea in time he desires to get rid of the primals as much as we do, so perhaps it's a temporary truce to destroy bismark?

If the garleans learn that those with the echo can turn themself into primals (like Iceheart), it will be not only the beastmen he will kill.

Doesn't have to know that yet, they already hate people with the echo as it is. It likely won't be the case but considering the beastmen in the background I imagine it would be around bismarks arc, garleans offering airship support to remove a primal isn't as crazy as it may sound as a desire for primal defeat is the one thing eorzea and garlemald have in common.
