No. Haha, sorry Grove! No. Yes. Yes. I honestly have no idea. He doesn't mention it, and no one shares his surname, but that's not definitive proof.
Hrm. It could be/can be? I don't believe there's a level requirement. It isn't strictly a tutorial quest as such, but those were added later anyway. I'll go with "yes" even though I don't really believe it was intended to be. (I could be wrong on that, too!) I had to go look to form a better opinion While he *is* in a building, it's really a stretch to say it's dong-like. I'll go with "no" for this one.
There are exactly 2.5 dong buildings in PoK. Are there other dudes with dongs in the immediate vicinity of the dude with the dong?
Uh oh. With that total, the answer might be "yes" even though I still think it's a bit of a stretch. No, not in the immediate vicinity, though it's PoK, so he's not more than a very short stroll from others. (Trying to clarify the interpretation of "immediate vicinity" I'm applying to the answer.) No. No. No. No.
