Ul'dah should have an aethernet shard by the market.

i tested this yesterday, only 3-4 seconds left on Sprint, so it takes over 15 seconds.

Really? It never feels that long when I'm playing. I had never timed it, but since it was a straight run, I guesstimated 5 seconds. Ah well, you live and learn. Still I think it's the fastest way from the main Aetheryte.
