Since this will be read by other new players in same situation...
go to begining of death realm. /die if you must.
Walk as far as you can. keep walking... if you can not find the way out, go back near begining, type in "help me please" and wait for someone to come running by... and then hit enter.
Also, I can not tell you how many times I am running through DR and I see someone standing there, I ask if they want help, and I either get lecured about them being busy (dude, walk into library or something, you do realize that people who need help stand there like that, don't you?) or I get no response. then when I am back in Hydlaa, I get a tell, they were afk for an hour or so..so can I come back and show them the way.
Log off if you are not going to be "awake"?
All else fails, follow those who seem to know where they are going, just dont be surprised if they take shortcuts you can not take.
Hope that helps some with someone.
