Ti-Fleek Lustrẻ, the GEOGRAPHY — A mountain range. Ti-Fleek Lustrẻ, an ancient phrase meaning “Teeth of the Lost,” is the name of a mountain range nestled within the cavity of the → Barren, also known as → Lost Lake. The range gets its name from the considerable impression it makes from the north: reflecting on the surface of the dead water, Ti-Fleek Lustrẻ creates a pair of jagged “teeth.” Rather than opening on the lake itself, they appear to be poised to open on the world beyond, adding to the mystique of the Barren. Ti-Fleek Lustrẻ is actually part of the → Western Mountain range but is separated by the southernmost expanse of the Barren.
