Storm King's Thunder
Lady Hariana Hawkwinter is a Waterdhavian noble and champion of Helm. She has dedicated her life and the fortunes of her house to serving the god of watchfulness. Her young cousin Nekademius ("Neko") serves as her squire. The two ride powerful warhorses, acquired from the finest stables in Amphail, and have recently been fighting against the hill giants in the area.
When the heroes first encountered Lady Hawkwinter, she was riding towards Waterdeep, along with a pair of young boys who had recently been orphaned by a giant attack on their homestead.
