Quests like:
"Come meet me in Limsa Lominsa! I've never been there before!" - NPC Residing in South Shroud

You teleport to them.
We assume only certain people can use the Aethernet/Aetheryte to travel.
How do they manage to beat you there, and how have they managed to read three books whilst waiting?

My simple question is:
How long does it take to teleport?
