A core....Unshielded

Misty, as you know, last month at research station [redacted], several Arcana agents were (accidentally?) exposed to the  unshielded core of a techthulhu prototype. What you don't know, is that during the following weeks, they all reported similar dreams of a pyramid hidden in the woods.  This tetrahedron was variously described as an object, a structure, or a machine by different dreamers.
 That was last month, and if you've been keeping up with my work, you know I've been traveling. I mention it again because we've made a breakthrough.  Acting on a hunch from one of our sensitives, and using records from the Arcana vault, we were able to pinpoint a probable location for the... The thing. The pyramid, tetrahedron, whatever it is.  We got lucky (good or bad luck?) and we found it. Or at least part of it. Or maybe it's a key? We're not sure what we've got yet. But it's something. Something big. I think it's already affected me. We moved it to the locus of an old anomaly site in Navarro for containment and study. Here's a picture from the brief time it was in my possession.​
