First Kizan War

This war was waged with the goal of severing the communication and trade link between Fargimdal and Rumaktharga. Much of the conflict happened in the Iruk valley. The Rúmil, aided by Angrod mercenaries were successful in cutting the surface supply routes. Far beneath, the dwarves cut passages, extending the Brother Tunnels. Once it was finished, it created a subterranean supply line between Rumaktharga and Dabul-Gind.

When steam was discovered, the Brother Tunnels became the groundwork for a line of the Kibar-Kûn rail network. This resulted in a protected and fast trade and communication route between the brothers of Taurelin and those of the homelands of Narbuzad.

The dwarves came out victors in this conflict with them fighting a defensive war which proved to be too costly for Rúmil. The elves pulled out of the valley. Angrod, another elven belligerent of the conflict, claims that the war was not lost, because the Iruk Tendril was not stopped and that it is only a matter of a few centuries before it links up with the Tulandur Tendril, thereby encircling Kizan, and leaving it isolated and vulnerable.
