Again Into the Great Ossuary
Are you headed back into the Scholomance, <name>? You've already paid such a great price for the use of the Divination Scryer - perhaps you'd like to take another one with you. With it, you'd be able to face the perils of the Great Ossuary once more.
By all means, have it. You've certainly earned it.
The entirety of this quest happens at Stormwind City
