Lake Kel'Theril is a small frozen lake in central Winterspring. The shores of the lake are home to the Ruins of Kel'Theril, which along with the lake itself is populated by many tormented spirits of the Highborne. Adventurers came here to hunt ectoplasm for their tier 0.5 armor quests.
Lake Kel'Theril Digsite
In the RPG
Once the site of a Highborne city, Kel'theril was reduced to a lake in the Sundering, and subsequently froze over in the following years. Many of the city's pillars are partially above the water line, but much of the city is submerged and encased in ice. Lake Kel'theril is now the largest body of water in Winterspring, and the ghosts of the Highborne that died there haunt the lake.
