You use description to build tension and character so well, Quinn.

A very enjoyable story, though the device of the message on the wall seems a little under-developed, as though it was perhaps added in a rush to tie up the narrative into short story form? I would suggest having the Necromancer gloat about leaving bait for Jay too, that he would soon have the blood of another (albeit less powerful) dragon too. That would add to Quinn's desperation to reach Jay, making the link flare brighter and be more easy to trace. Foiled by his own greed?

I was really pulled into the story though, well done.
