Sakh'arran's courier reached the Arch four days after his note to the Order's Threian chapter went out.
The verification had moved faster than anyone expected. The Threian chapter's seneschal had already begun compiling detailed observations before Khao'khen's request arrived.
Vor'gath read the compiled notes at the instrument room's secondary desk, with Aliyah beside him and Darak's notation materials open between them.
The Threian-side reports described darkening at three locations along a forty-mile band of frontier territory.
In each case, the darkening was not surface discoloration. It sat inside the stone itself, visible at certain angles of light, exactly as Denn had first described it months ago.
"The depth of the darkening," Vor'gath said. "How deep, relative to the surface."
Darak checked the notation. "The seneschal's people measured one location precisely. Slightly less than half the depth of the section Denn first found."
