To change from Aldors to Scryers you would see Arcanist Adyria @ 54.22 in Lower Shat, and do the "Voren'thal's Visions" quest repeatedly.

I wouldn't really be too concerned bout it just yet as
there's some quest you cant do till you're lvl 65 and then the rest is lvl 68 and up.

OK so since I am lvl 60 I can still go to the scyres side of the city without being attacked right. Does anyone know if there is a enchanting trainer in the aldor side? But I think I made a good choice with the aldors I get better patterns for tailoring...

ok so if you pick your alliance with one side don't go to the other side  Itried yesterday and the guards stoped me a teleported me outside the city

Yes, they will become hostile.

Did you mean you died? Or did they just teleport you out?

they teleport you out. you get banished then teleported out. lol. Where can i go to learn enchanting? I can still go to SW but after that where?

Are u horde or alliance?
if horde, do scryers.
if aliance, do aldors.

thats pretty stupid what the person said above me...
go scyer if you are a caster! they give you nice rewards at exalted and reveared. aldors stuff are focused on healing, not really anything good for a lock.

i am alliance. I might start doing quests to get nuetral with the scryers. But not too sure yet.
