Ma'ar does not interrupt them. He manages a much calmer conversation with Urtho. They're both carefully civil, distantly courteous. Like strangers.
His troops are withdrawing and should be entirely clear of Tantara's pre-war borders by tomorrow night. Urtho's army is still guarding the Gate-terminus and the border; he agrees that this is a reasonable defensive precaution. They do a very frustrating dance around the topic of phasing out compulsions and blood-magic in Predain. Blood-magic he can order stopped now, that can be reassessed now. He's a lot leerier about the voluntary compulsions as oaths of service; he thinks it's doing important work, that his troops are loyal to him and obeyed his order to retreat and surrender even though many of them have lost friends or family to Tantara's army and hate Urtho's entire country, and they must have thought he had lost his mind.
Urtho reluctantly agrees that he won't force Ma'ar to undo all of the current loyalty compulsions, as long as he stops doing any new ones. Ma'ar agrees to this.
By the end he's so tired and his head is spinning and the ship's interior feels oddly fake. It doesn't help that the concept of being out in the vacuum after the sky stops being air is an incredibly surreal and fake-sounding one, but also the effort of not having any emotions and maintaining his best attempt at a diplomatic facade with Urtho is so draining. He feels a bit like he's forgotten how to be anything other than a careful mask over emptiness.
It's good news, he tries to tell himself. The war is over. This is exactly what he wanted all along.
It feels hard to really believe that.
Some of the mage-recruits speak Tantaran, so he can ask them for a place to sleep, and he locks the door and puts wards on the walls and then lies down on the bed and closes his eyes. Ironically enough it feels like he's also forgotten how to sleep, but it happens eventually anyway.
