"There have been no rumours as of yet," the elven woman replied as she contemplated the angles, "Though I am sure to contact you if this core becomes available.  I'm sure the nobility would like it back and I could always use additional favours."

Yes, there certainly was a possibility the sentinel could identify the Blood Angel if his core could be restored and the body repaired.  Mind you, it was just a possibility.  The Blood Angel was bad for business, bad for all business.  When the thieves and the rogues were scared to come out at night your city had a real problem.  If she could find this core it would be helpful to her and each favour she earned made it more likely she would earn herself a true ladyship.

For a brief moment she considered asking for a piece of the fallen sentinel, or perhaps some leaked fluids.  Unfortunately, asking the question would tip her hand, proclaiming to all the world her secret hobby of scrying on one and all.

"I shall make inquiries." she reiterated, making the decision not to share.
