Its two sources were the Hill of Himring, via the Little Gelion, and the Ered Luin, via the Greater Gelion. It then passed south, dividing Estolad to the west from Thargelion to the east, then was crossed by the old dwarf-road at Sarn Athrad ("Ford of Stones"). It then passed into Ossiriand, the Land of Seven Rivers, where it was fed by rivers Ascar, Thalos, Legolin, Brilthor, Duilwen, and Adurant, all rising in the Ered Luin.
Gelion then passed by Tuar-im-Duinath (the Forest between the Rivers) and emptied into the Great Sea Belegaer.
In response, the Gelion N put away the particle cannon and two short gattling guns folded out of the back of its thighs, followed by the rest of the barrels from the calves.
Once the Gelion N stood up all the way, all of the external armor was gone, revealing a bright layer of solid diamond, which glinted a bright red in the morning light.
Gelion N then sprouted large spikes on the bottom of its feet and dug them deep into the pavement, using its hands to hold the angels head in place and its butt to hold the rear in place.
