Orul's Crypt Secret

[doubleaction]

When you enter the Sanctuary portion of the crypt there is very clearly a secret button on the wall "inside" the teleporter (the one you arrive from). Anyone figured out how to get this? I've noticed the teleporters shut down when you defeat the boss of the area (Fighter killed him one hit with a crit from Bane's special attack, but I digress), but you can't get back in without them (?) and you have to re-activate them to escape the area, anyway...

yes

There's another secret button that deactivates the teleporter so that you can get to that one. IIRC Looking into the teleporter just turn right.
