The House of Regents is a collective of House Wardens. Elaboration needed. In the case that the reigning monarch is absent or incapacitated, the House of Regents will step into power during the interregnum. It is otherwise an inactive governing body.
Background Information Draft
Due to the fact that the Empire is split into four independent states governed by an Imperial House, the House of Regents requires that the House Wardens unite in times of need.
Additionally, if the royal bloodline is to die out, a House Warden is to become the next monarch.
