I think the lore may have changed, seeing particular race restriction where as now that list would need to be greatly altered. Also, teleportation still exists in Aeria, look under Secular magic schools, and there are two entire schools devoted to teleportation: Translocation (short/long range) and Regalication (Portal/Bringing both spaces together). Hell, it has its own devoted college of study, called Planumancy. = P
Just saying, I believe this lore exists, has been updated, or been outdated. <3
EDIT: The only thing I'm not seeing so intact from this post in modern Aeria is common-place usage of the 'short range teleport', though, truth be told; I feel maybe this is a good thing, melee combat is an intricate, and delicate exchange. This is exponentially so when dealing with group combat. I feel for the sake of sanity, group play, and for the survival of P2L within the server, maybe heavy use of short range translocation is best left undone.
Also, Regalication ftw.
