The Tsaeci ate the Akaviri humans. Whether this means they actually ate them or just assimilated them, it is unknown.

The Dragonguard are long dead. You said the Dragonguard, not the Tsaeci, not the Kamal, not the Ka' Po' Ton, you said the Dragonguard. I am answering the question.

Only one Akaviri has turned into a Dragon, and he does not have a Dragon soul.

That's LOTR. This is TES.
