It's just a jump to the left....

Because I can!  I took my new little rogue for a plunge off the side of the Sanctum bridge for the base-jumper achievement

And discovered, that if you jump in the exact centre of the bridge, it counts as both jumping from the Sanctum side _and_ the Silverwood side.

And in fact, so much fun you did it twice is a lie!

I _wish_ I had known this when I did it in a suicide run on my Defiant warrior.
