Tarn Mira, also called "Bezdno" (Slavic for "Bottomless"), is one of four lakes arranged in the shape of a trefoil in Mil Tracta. The lake forms what would essentially be the stem of the cloverleaf. On the north shore rises Tor Zireael. The banks are very steep and it is surrounded by a dark forest. It is on the frozen surface of this lake that Ciri finally killed Rience and Stigward.
