Recruit
Are you sure Vaegir knights are supposed to be mounted? I've tried upgrading them repeatedly, and the Vaegir knights are always on foot. Granted, they're a damned near unstoppable force in large numbers on foot, it's just not the same. And it's not just me, either. I was planning to exit anyway, so I attacked a Vaegir prison train for the hell of it, and their knights were on foot as well.
