Toghalann, the Knight of Spring, handles matters internal to the Court. Xey are also the first major fey that those visiting the Court of Spring must speak with, that xey might learn of potential petitioners - and would-be warlocks.
Xey are also charged with undertaking missions that the King, Queen, and Prince cannot resolve themselves. Whether this is by ancient law or the whims of King Ormharach, xey are... well, indifferent to. A mission is a mission.
