The great falls of Fulgur were one of the natural marvels of Lethinus. In the name of the Omnissiah, the Adeptus Mechanicus destroyed the falls in order to harness the great power released in the passage of the masses of water. The hydro-electric plants of the Fulgurine massif provide power for most the heavy industry on the planet, as well as communication and control hubs. Possession of the hydro-electric plant region, will no doubt prove valuable in a war for dominion over Lethinus.
