Indus was a gnomish member of the Council of Tirisfal 2,600 years ago. She preceded Erbag as one of the first gnomes recorded in history.
2,600 years before the First War, she was the group's gnomish representative in her day. Not only was she a respected, powerful mage, but following her people's penchant for tinkering, she was also known as "the inventor" in Dalaran. She was an associate of founding council member Meryl Winterstorm. She, Meryl, and the rest of the surviving council would empower the first Guardian of Tirisfal, an orphaned half-elf and talented mage named Alodi. One of the machines she used may very well have been the first hot air balloon.
