This route isn't exactly on Ered Lithui, but rather an unnamed formation just to the south. Hike up to the hill at the start of Middle Earth. Instead of taking the trail up to the Hrum Hroom area, descend back towards the Outlets slightly until it is possible to contour the rocks heading west. This route is on the face just to the right of the Guardian, which is the obvious dihedral that is to the right when contouring the downhill side.

Climb the face to the right of the dihedral. Follow the 4 bolts to the fixed anchors. Rappel with one rope.
