Jantoo

Jantoo was a philosopher working in Waterdeep in the mid–14 century DR. She considered by many to be the greatest philosopher alive.

Activities
Two of her most famous papers focused on free will. One proved conclusively that mankind had free will, the other proved that it did not. Jantoo could either argue for or against any issue, depending on her whim.

She publicly said that she would marry a man who could defeat her in a debate, and hence remained single by 1358 DR.
