Getting around in Agartha sucks. Sure, the various Solomon Island zones are varying degrees of convenient, but getting to the portals for Egypt is a hike, and Transylvania may as well be in, well, Transylvania.
Getting back to the city portals is easy enough (just fall), but heading back out into the field is a pain. Worse yet, the hike gets longer just as you hit the endgame zones from which you'll frequently want to be coming and going to do dungeons or use services in London, NY or Seoul.
I've heard rumor of 'shortcuts' in Agartha to the various portals, but am too dense to find them.
How can I get around Agartha more quickly? Especially to the Transylvania and Egypt portals?
