Valen and Aleera see the winged man-cat-thing leap into the air and take wing again. The creature lands about midway between the village and the keep and waits for the group to get a bit closer before speaking in a normal, though deep and growling, voice.
"In answer to your questions, dwarf, I am a Lammasu and the guardian of this place. The black structure is a regretable necessity. It was built to..."
The lammasu suddenly looks troubled when he sees Aleera approaching, "By your presence here, I must assume that Piper's plan did not go as intended."
Aleera raises an eyebrow and looks at the creature warily, "What plan?"
Varol takes a deep breath and continues, "The black structure was built as a prison to contain that which cannot be killed. An enemy of such destructive power and overwhelming malice that not even the combined might of The Ten could defeat it. And so, there it lies, imprisoned within a building made of the forbidden shadowstone. Orcus is its name and it must never be allowed to walk the world again. That is why I am here, to watch over it."
The lammasu turns to Johen, "There is another enemy that can only be contained, not destroyed. Azilyk. Piper, one of The Ten, had sought to imprison her within this obelisk as well. She has a primordial link to the Dagger of Souls, the murder weapon of your mentor, Johen. The Dagger is an indestructible artifact of great evil. Piper sought to manipulate events to entrap Azilyk's soul within the Dagger and then use the Dagger to transfer her into Orcus' prison, but that appears not to have happened. If you have questions for me, I will gladly answer them. First, however, I must apologize for the part I have played in this. It was I who brought the Dagger to Turen at Piper's request. Once it passed out of my possession, I could no longer control what became of it after that...but that does not absolve me of the guilt for the part I did play."
