The Attalya Mountains are a mountain range stretching across the western region of Lenya. They are grouped into northern and southern ranges separated by the Cliffshear Canyons.
This expanse contains some of the tallest mountain peaks in Esterfell.
The name is Elvish for "two-footed", referring to Tillë Peak and Taltol Peak, twin mountains that stand high above the surrounding terrain and which are among the tallest points of elevation in Esterfell.
