Aeron
Aeron is a dwarf who for most of their association held the same open working relationship to the Low King as Rufus Drumknott does to Vetinari. However, since Rhys Rhysson elected to come out as Low Queen Blodwyn I, the similarity ends there. (Unless Drumknott and Vetinari have the sort of association only hitherto speculated about in the dodgier sorts of fanfic). aeron is now officially, as of Raising Steam, the Consort to the Low Monarch. Dwarfdom has, in the main, accepted this.
