Mirastir was shocked by the death of his comrades, no matter what caused it, but what could be done? All that remained was to hope that the Artery would accept them into its halls (and he prayed to both the Artery and Leilana).
The strongman wasn't particularly interested in politics, so he didn't react much to the rumors of war with Lisliar and the squabbles between the church and the Airisufir. If something like that is happening, then those in power will sort it out. His task, as a Helionite, was to participate in grand and glorious deeds, to be a hero. Although, to his regret, he wasn't getting much opportunity for that – instead, he had rather boring work, helping people out (but what could he do, he wasn't a medic?), working in the mines (not very healthy, but better than doing nothing). And yet, for the sake of his beloved nation, he persevered, and there was always hope that he would get to fight evil enemies in the glory of Airisufir, the Artery, Leilana, and, of course, Mila, who, with all these wanderings, was undoubtedly getting closer and closer.
Did I have enough air for the squid rings, Revan? Count it up.
And all the prayers for everything that has happened. I prayed every day.
