Yustianna was a pirate born of a Skelliger from Clan an Craite and a captive woman taken during a raid. In her time she was feared on the Continent from Ofir to Zanguebear. Known for her skill as a navigator and unmatched master of various weapons, she quickly became the terror of the Great Sea, and when she returned to Skellige, they say this cave is where she hid her loot.
