I thought about that too, but my first writ and current writs bypassed auridon, grahtwood, and greenshade. I actually didn't have Veylyn harbor or any of that zone discovered... I suicide ran myself there from the one wayshrine I had discovered in reapers march lol.
At level 17 my dude ought to be just now entering Grahtwood according to the quests I've progressed.
Thanks for the link, it's slightly clearer now. Still eft wondering why I bypassed the first 3 drop offs with little story progression and not the 4th, which would've put me in reapers march. Maybe the system doesn't care until this point....but I'll progress slowly and keep trying. Thanks everyone!
