A member since the Old Board, he encountered legal difficulties which people are reluctant to expand on. He then returned to us, and there has been much rejoicing.
Grey Wolf is noted due to his penchant for royalty, especially in regards for all of the members of the former Kings/Queens of Europe, and his (in)complete research can be seen in this thread: Grey Wolf's Royal Family Trees - Click Me!

When Fortune City went under in 2012, GW thought that he had lost the entirety of his very first AH site, Infinity Wanderers. Luckily, as documented in this discussion, archive.org's Wayback Machine came to the rescue. Most of GW's older writings, as well as contributions to the site by guest authors, had been successfully retrieved and preserved.

Since Grey Wolf is regarded as a Legendary Board Member, he is one of the non-Members of Parliament and those with no party affiliation to be appointed to the AH.com Cabinet by Acting President Sargon.
The Coronis Lupus Incanus was named for him, as he was for a long time AH.com's Most Postingest Member.
In AH.com The Series, he is usually depicted with a unicorn and a bottle of alcohol. He is also one of the original crewmembers of the AH.com Ship. When writing the AH.com The Movie, Psychomeltdown considered Grey in the captain role, which was eventually given to Doctor What.
Grey appears in AH.com Wars as 'Greyce Wolfu', the Mace Windu analogue. He is perpetually confused by being described as a 'badass motherf__ker' in the script, as he is uncertain what this actually entails.
Rather inevitably, he also appeared in Luaky Commer as the Remus Lupin analogue.
In Max Sinister's Stories from the Chaos Timeline he appears as Gray Wolvertone, court chronicler of New Albion. A kind of appropriate cameo role for him, as his character there also mentions the country's “Plethora of Princes”, in a nod to Grey's own TL.
And finally… of old, he still stars as Captain Joachim von Wolferein of the cruiser Regensburg in Jim's Letterstime series on the old Warships1 Naval Fiction Board.
