This might seem like a really stupid question, but I'm really new to the GECK. Where can I find the Courier (the Player Character) in the GECK? Or is the Courier not there?

Player "Olo, Bendu Olo" [NPC_:00000007]

PlayerREF [ACHR:00000014] is a special REF, not to be found in the ESM.

I'd avoid touching the player record in a distributed mod if at all possible.
