In Curse Of Strahd, Helwa's tribe took in a wandering Izek Strazni at the request of the elders. Though Helwa did not respect the outsider, she could not deny that he was a match for her in terms of strength, and placed him in charge of taking care of young hunters; his ability to speak the Common tongue also allowed him to communicate with adventurers and everyday Barovians.
Helwa would later encounter Izek and the rest of the Heralds of Dawn while holed up in the temple's annex. Bearing a Roc feather and claiming to have killed the giant beast, Izek impressed her into allowing them to accompany her, and they joined her barbarians in hunting for Bloodhorn. Lead by Ghalwin of the Grove and Pip, the adventurers quickly found their charge, and Helwa relented by indicating she would support Izek in a bid to become their tribal chief.
The barbarian protected Ezmerelda D'Avenir's Vardo as they descended Tsolenka Pass, before disappearing off into the forests. She remained at the hill, eager to impress the Lady of the Mountain on her own terms after the Slaying Of Strahd.
