Maps, Artifacts, and Other Arcane Magic, Dowser #5

I also inadvertently released a rival who was definitely unhinged, way more powerful than me, and obsessed with harnessing the deadly power of the artifacts I’d been tasked by the guardian dragons to collect.
Add a sexy sentinel and a nearly immortal vampire to the mix, and what could possibly go wrong?
Knowing my luck, I was about to find out.
