Freeshooter. There are ways out of the city. The Kalesians won't force everyone to stay, and once the Inner city and fortress have been taken, they will let citizens return to their homes. If we'd suggest something for escaping: Hide, wait for the city to become Kalesian domain, then escape afterwards. Mind you, we'd still recommend that you do something like finding an air evoker of some sort to catch you from dropping to your death.
Also, one more tip: We know the "Empress, may she live forever,"-bit irritates you. But that should not reflect onto your character until after he actually comes across it himself. It'll make him a much more believable character. From his experiences so far, he has never come across it.
We personally prefer not to kill or maim other PCs, aside from when they foolishly step in front of a highly focused weapon of great power of course. Yes, that is basically what Markul did when he interfered with the Shaker.
One final tip: If you're unsure about something, if you wonder if it'll go across well with someone: Ask. We personally will gladly answer questions about lore and/or posts that we've worked out. If the idea is good enough, we'll even gladly help work it out, no matter how detrimental it'll be for "our" forces.
