Eldy Gru and Erl both attended Harry's birthday party at Arctis Tor, didn't they? Erl invited him hunting, if I recall.
ahh.. I don't recall lol. I Thought only Gruff was there? And Kringle talked about EK? I'm going to have to reread that.. unless someone has their book handy. I was thinking just now that EG sent EKs regards to Harry, which would be another irony.. gonna go find my book lol.
*Nope, your right, they were both there... Mmm,
The only other person I thought of for him was his possible original person being Arthur. isn't there a Woj he used to be human? Lol, and EG I think is Ole billy goat shakespeare. It would explain why he was able to make Titania see the purpose in her tragedy, it's a particular specialty. But someone else whose been onscreen? Mmm...
