Alushinyrra is... awful, actually.
Oh, well yes, what they did to Trever is awful too. Sosiel hates it. But - it could be worse. Sosiel was terrified, when he heard that Trever had become a Hellknight, that the war in the Worldwound had killed his brother - not his body, if he died in battle they would meet again in Heaven. No, he was afraid that what he admired in his elder brother, the parts of his soul that would have made Pharasma judge him as part of Heaven, had died. And truthfully, a gladiatorial arena in an Abyssal city is not a place where he'd have expected to find those glimpses of Heaven. But he spent so much time thinking of that, and worrying about it, that he did all his grieving for Trever in advance. And then when he finally found him... his brother, his elder brother who showed him how to paint, who went to fight the demons at the Worldwound to keep them out of their homeland, the reluctant paladin... he rose out of the filth of the Abyss one more time, and defied every demon in the city so that Sosiel might be safe. If Sosiel does not meet that man again in Heaven it will be because Sosiel's besetting sins became too strong.
