Blue
Ravenous Bugblatter Beast of Traal
The DM for my OotA campaign limited us to the PHB and SCAG books, a couple of us are lobbying him to let in the EE spells, he's going to revisit the idea. Even if all the patron options were available, I still would have chosen Archfey for the flavor of it. I'm a huge Dresden Files fan. My Tomelock has the Leanan Sidhe as his patron, my Warlock for the OotA campaign has the Queen Of Air And Darkness.
Hell's Bells, that's excellent! I was just theorycrafting mechanically, but a strong concept for your character should always trump that.
