The Minakaan Lake was a prime target to relieve the world of its thirst.
Sands have always smothered the Hollows. Centuries ago, water covered the sand. Greenery flourished abundantly along the shores of the Minakaan Lake, and the waters provided sanctuary for a myriad of beasts and plantlife. Over time, however, the lake was unable to sustain itself under the unyielding heat. It began to evaporate. Lush greens decayed to the dull yellow of a lantern's fading light, and the bright, sparkling azure waters paled to the mottled brown of cracked mud. Life no longer belonged here.
