As told by Tani: With our tigers we landed we in a a wayless sand desert. We decided to flee the burning sunlight, the thirst and the hunger to the far mountains, which we could see far at the Phialae horizon. We rode an painful week by the desert. At the foot of the mountains we discovered a broad valley that we found blocked by a transverse wall. A wall, one hundred steps pendicularly rising, an artful bow striking from mountain to mountain. A miracle, built from elven to primeval times. Riding on the tigers we could climb the mountain flank. Beyond the wall we reached a saving lake, which was accumulated by the wall. On the wall we established Castle Dam.
