while designated regents can be lore-based, I'd like to propose that we tie it to the Centralization Policy I proposed in the Law Review thread. Specifically, only centralized and authoritative realms should be able to designate who becomes the regent, as autonomous/decentralized/balanced realms would have a power struggle to determine who becomes regent (and the outcome of this behind-the-scenes "power struggle" is abstracted as the almost-random-selected regent).
