Temeraire is losing his Divine Wind and his flight, so he'll be incredibly cranky while he's landbound! This will also cut down significantly on his ability to get to the shell's edge to feed himself, as has become habit for him by now, so he'll be really very hungry on top of his frustration.
He'll also be losing his ability to learn languages quickly, though he'll retain what languages he does know at this point. By now this extends to the written kedan language, so he may be offering his services as a considerably more trustworthy translator than any of the kedan in return for food. Or doing anything he can in return for food, really. He'll still be retaining a level of strength proportionate to his size, so with a lot of the superhumans presumably losing their strength, he might be of some use in that regard!
