Kalecgos, one of the few surviving blue dragons, is the first boss in the Sunwell Plateau. He is being corrupted by Sathrovarr the Corruptor, a servant of Kil'jaeden. He often assumes half-elven form under the name of Kalec.BackgroundKalecgos was an investigator sent by Malygos to Quel'Thalas to locate what appeared to be residual energies from the Sunwell, believed to have been destroyed by the Scourge some time before. What he found was a strange young human named Anveena Teague, who lived with her parents outside Tarren Mill. While in Tarren Mill, they were confronted by the Scourge led by the elven traitor Dar'Khan Drathir, who sought the power of the Sunwell for himself. Though Anveena was kidnapped by Dar'Khan, Kalec discovered that she was in fact the avatar of the Sunwell, and aided in the final battle that led to Dar'Khan's defeat. Afterwards, the previously-enslaved Korialstrasz - Prime Consort to Alexstrasza, the red Aspect - explained that he had created the illusion that was Anveena, in order to prevent the Scourge from obtaining her power. When Lor'themar pledged himself to keeping Anveena safe, Kalec decided to remain behind as well as her protector.
