He was summoned long ago to this world, during the early Albion campaigns against the Caledonian uprising which was a war between two human countries on the edge of the dragon empire, one of whom used demon magic to quell a slave revolt, and it turned into a 100 year long war... which for the most part was of little interest to the Empire which was busy placing the Er'aura.

He broke the contract he had signed with the summoning mage when he fell in love with a Caledonian human slave (male). This caused him to be banished from the demon realm, in anger/annoyance regarding his banishment, Kerwin in the form of a human woman and his lover started hunting the other demons that the Albions were using. This lead to his lover's eventual death; but by then Kerwin had made a pact with the leader of the slaves to help in the war. He stayed to see out that pact. Over his years with the Caledonian's he developed a deep hatred of demon, and other slave societies, as he saw their eventual corruption play out era after era. There is some indication he may have been involved in the revolts in Sparta, and the slave uprisings in Rome as well as the slave uprisings in the American south in the 50's/60's CE.

In his early years on this world he and his Aradan were called the overlords hound, though his Aradan were always the public face of the hound to the Caledonian people. In the time of Malcom the III the youngest son of the Stewart family made the pact with Kerwin and becomes the person to makes the sacrifice that topples the curse on the Albion throne in return for his protection of the Steward line.

By the time the pact had lapsed the magic died and he was trapped in the human world without a gate to get home. He became a warrior and hunted demons and 'evil' mages early on in history, and this allowed him to stay awake, even gain in power despite the lack of magic in the world.

He became part of the Knights Templar until they were disbanded - and is one of their secrets that has been lost to history.

In 1917 CE he was in a bombing of a French church - he was the only survivor. This was written about as a miracle, and Ryan read the article in a paper and sought him out after that. After much pushing on Ryan's part, Kerwin finally admits to being awake all those years, and finds in Ryan an ally who still believes in humanity (something that other's that were constantly awake lacked, in Kerwin's opinion).

The two of them joined forces and started helping the dreamers, making their lives a bit more bearable. (Something that Ryan, as a Jesuit priest, took as an extension of his vows to the church).

In 1945 CE Kerwin joins Ryan to form IS51, finding an even greater need to assist the people that the Nazi's woke.
