As a child, Milya d’Orien was fascinated by the lightning rail, and would often stow away in cargo carts. Today, she spends her days riding the rail. Milya is fiercely protective of “her” passengers, and shows no mercy to anyone who threatens their safety. While away from the house, she often roams the lost lines: lightning rail routes destroyed during the Last War, including those in the Mournland.

Thirty miles inside the Mournland, 100 miles south of the Saerun Road, is a mineshaft into a low hill. The only sign on the entrance is a Cannith seal, marking the secret facility below as that house’s property. Although Whitehearth was well known during and before the war as an ancestral Cannith forgehold and weapon research laboratory, few know what wonders and horrors this place holds.

Merrix d’Cannith of Sharn has information indicating that Whitehearth’s artificers enjoyed a breakthrough just before the Mourning. He has dispatched teams to locate Whitehearth and recover its contents. So far, none have returned.

Inside Cyre, Whitehearth might be one of the oldest and most well known of Cannith forgeholds, but it is not unique. Several more Cannith facilities still exist in and under the Mournland. Their purposes might be different from Whitehearth’s, but their treasures still await liberation.
