The Lords Commissioners hold the Royal Commission of King Mater, and since 1728 PD have exercised the powers of the monarch of the Kingdom of Heghom in his name. King Mater was last definitely seen alive in 1733, and was probably lost at sea. However, as he had no immediate heir and the matter of his succession was a very divisive matter in the Noble Council, the legal fiction of his continued reign, and hence the validity of the Royal Commission, remains. In practice, the Royal Commission is developing into a de facto self-perpetuating Directory, taking the place of the monarch in the Heghomic system of constitutional monarchy. Although this has not been without controversy, the majority of the Noble Council seem to prefer this status quo to any alternative (e.g. declaring the king dead and passing the Crown to various distant relatives) that has been seriously considered. Popular feeling is more mixed; some with republican leanings have considered the sharing of sovereign power in this way to be something of an improvement on a monarchy. However, the institution of the monarchy is viewed quite positively among other parts of the population, who would like to have a traditional sovereign once more.

The internal deliberations of the Lords Commissioners are private, but they are known to use a simple majority vote to make their final decision on any weighty matter. They have also sometimes internally delegated decisions to one of their number, with the others agreeing to abide by the decisions of that commissioner on the matter, for the sake of expedience in time-consuming but largely uncontroversial matters. The Commissioners consider three to be a quorum in an emergency.

From 1728 to 1744, three Lords Commissioners died (one being replaced by his wife who succeeded to his title, a legally questionable maneuver to keep a quorum), but no new members were actually commissioned. At that point, the remaining members decided to interpret their commission as allowing them to appoint new commissioners, and two Noble Counselors were commissioned. The primus inter pares of the Royal Commission is its most senior member, the Lord Watts.

The current Lords Commissioners are Lord Watts Count of Besbet, Lady Pilsen Duchess of Nisthom, Lord Tuman Archduke of Walby, Lord Heget Count of Reynom and Lord Wiscon Baron of Averet.
