Eldritch Lake was a place of pilgrimage for the Templar Caste. Before the Zerg Swarm ravaged Aiur, pilgrimages to sacred places across the planet by members of the Templar Caste were a common undertaking. Many of these pilgrims traveled to a secret lake high in the mountains that was thought to contain mystic properties. Some went seeking serenity, while others were seeking self-awareness and a greater understanding of the universe.
The lake is also the source of the bottled water known as Eldritch Spring.
Eldritch Lake acts as a multiplayer map in StarCraft, supporting two players. Air support is vital to even reach one's opponent.
