The Lutrosi Mountains (IPA: /ləˈtɹɒsi/) form a range that covers a broad swath of south-central Epiros. The range reaches from the northern Siladent Forest in the east, westward along the northern boundaries of Thesion, the Forest of Piges, and Chasadon, before turning south to form Chasadon's western border. The range finally terminates beyond the western end of the Aphieron at Estemmen Bay.

The Lutrosis are a wide range and reach a long way into central Epiros, forming a natural barrier between Lokren and the kingdoms of the north-western plains.
