Lord Thymon is a lovecraftian abomination.
Thymon was once one of the improbable horrors inhabiting the Void Between Worlds, a sort of time monster with dominion over whatever time exists within the Void itself — though his "ominous abomination" facet is somewhat undeserved by the silly hat he wears at all times. Personally offended by any forays into the Void, Thymon had no qualms with breathing fire at dimensional-travelers until they went away.
As (unlike many other voidships) the Crew of the Copper-Colored Cupids's Fog Ships were not fireproof, they came to see Thymon as a great threat to themselves, and eventually assigned the Department of Problem-Solving with taking care of the Thymon problem. In the end, with their trademark to-the-point-ness, the Department resorted to hitting Thymon with a Cupid Arrow, which has made him love the Cupids unconditionally ever since.
Thymon now works at the Department of Postal Services, where he is able to sort mail much faster than the usual Cupid workers.
Behind the scenes
Thymon first appeared in the 2019 short story Lord Thymon and the Department of Problem-Solving.
