Warlock character idea

Hey there! I'm noodling on a character idea, of a Warlock of the Blade dedicated to an Archfey along the lines of the Erlking, Lord of the Wild Hunt. He's almost almost a force of nature, but not a god. Leaning towards either a Kitsune, or a Dryad, or an Au Ra (however you spell the ram-folk).

However, before I go too far down this idea, I thought I should check and see if this being even makes sense in this world?

That sounds great!! Just let me know how much interaction you want him to play and how manivalent (so?) you want him to be.

I posted my character sheet. My warlock is Donnall, minion of the archfey, The Erlking. The Erlking's Wyld Hunt overook him one night in the woods, and left him changed. To what extent he doesn't quite know yet, but it has left his mark. He has a predator's nature now, and savage urges that frighten him. He sees every social interaction as a predatory/prey dynamic, now.

Cool looks good when do you want to start your prologue ( like before the pact with the walking or after)
