Toshley would like you to use the Light Trap to catch 15 Razaani Light Orbs. Return to him at Toshley's Station in the Blade's Edge Mountains after you have done so.
15x Razaani Light Orbs trapped
The Razaani ethereals have been playing with some interesting technology at Razaan's Landing to the north.
I'm sure they won't mind if you use this trap to take a few samples of their little pink floating light orbs? They're probably only for decoration anyway.
The trap has a special property to it that when opened should attract one of the floating balls towards it. Of course, it'll probably also alert the Razaani to your presence.
