Maps involved: Desert portal, map containing the Sanctuary of Disciple Torizaela.
Spawns on -both- sides of the transition are sometimes right within instant-agro range of the trans, as I discovered the other night. On Torizaela's side, there were a number of snakes mere steps from the transition, and after racing past them at high speed to trans before they caught us, we found a moderate number of sand demons on the other side. I myself was blinded by the nearest before I even loaded, and had to run for the Conclave like crazy in total blindness while someone else ran interference for a number of them, resulting in both of us nearly dying.
Also on Torizaela's desert map, there is a spawn point directly outside Torizaela's sanctuary, meaning anyone leaving it and climbing up the steps risks instant gankage by Withered Marauders and such.
