The lightning rail is an international train line operated by House Orien’s Transportation Guild, which connects many of the major cities of Khorvaire. The technology dates back almost 200 years; the first rail went into service between the cities of Flamekeep and Fairhaven in the year 811 YK.

The wondrous lightning rail system once linked the far reaches of the Kingdom of Galifar, prior to the Last War. Now the system is divided, split into eastern and western circuits. Reestablishing the conductor stone paths across Scions Sound and the Mournland is often discussed in the halls of power in the Five Nations, but formidable challenges are involved.
