Only the East-gate, the "Doors of Morning", were kept unlocked. They opened toward Moinarlin (Q.: "Dear Exalted Mere"), a pool fed by three waterfalls and the birthplace of the river Cuivisîr. The Doors of Morning actually opened onto a grass-covered road that wound under the great cataract spills out from Moinarlin. The fall formed a watery arch that gave birth to a virtually perpetual rainbow. The Cuivisîr was one of three major streams emptying into the great lake of Helkanen. Helkanen was all that remained of the Gaer Helkar. Its cold shores formed the core of the Avari's guarded homeland.
