Mri'Thas stoic face didn't change at all from the beginning of Kama'zer's story. He takes his hands out of his long sleeves. "I was born in a cadre, trained in the use of magic, and sent to Ea to fight the Githzerai to death, which I did proficiently, merciless, and with no truce. My cadre was slaughtered by the crusaders, years ago. I survived, barely.
Someone rescue me, and taught me the way of tolerance and peace. But these are not peaceful times"
His gaze fixed in the woman, he moves his fingers in a small circle. Two orbs of shiny orange forms before the wizard, like small suns. As the mage gather his hands in a mutual grip, both suns merge. "Under one sky" he says, testing; his hands ready to unleash a terrible spell. If Kama'zer was a githyanki spy undercover, he'll have to annihilate her swiftly... given that he was able to.
