Paragon Lef is a Gor'tog Paladin who was raised from the dead by Marstan. It's believed she died sometime during the elven human war. Her child was killed, estimated between the age of 6 or 10 years, and is buried in the Crossing Cemetery. While she is a very capable fighter, and quite friendly, there are some personality quirks attributed to her being raised from the dead.
Lef's child is believed to be the shade that Marstan often used to run errands and communicate with his allies. It's also believes that the child was the Shade seen in visions while Marstan was being tortured in Sorrow's Keep.
