Sneak past all the guards to reach Doran the Crow ( 79, -3, 29 ) /waypoint 79, -3, 29. If you are caught you will be transported back to the zone-in and will have to try again
All of the guards have huge detection ranges; however, according to a dev, each time you are caught the range decreases slightly  Guards everywhere, can see through invisibility. Wander constantly, turn continually. Expect to be caught dozens of times.
The guards cannot "see" directly behind them.
The guards do not detect you inside buildings. Use them as places to watch the guards pathing and turning patterns near the fountain. Jump behind the rubble pile directly across from Doran's room and run into the room, clicking on the door, right after the guards have faced away from each other. Also note that none of these hints really help you. It is all rng to get through, you will take several dozen or more tries until it randomly lets you thru.
Speak to Doran and make your escape
Doran will follow you. The guards aren't interested in sending you back to the gate now. Prepare to fight them.
Go to the fountain and find Captain Xalkastiz (level +2, yellow con). Kill any remaining guards near the fountain and he will appear. Fight him to nil and Doran will knock him out
Make your way to the zone-in. The quest updates just before the zone-in
NOTE: Currently, it appears that if you are slain by Capt. Xalkastiz, you will not have the option to respawn. You will in fact, be locked in place, dead, inside the zone and have to use /quit to leave. Wait a few minutes and log back in. You should now have the option to revive in Freeport at one of 4 locations.
