Valghast is a large winged lion, serving as a mount and companion to Ygva, a powerful witch. With a savage appearance, he possesses the ability to assist in travel between the upper world and the World Below. Valghast's imposing presence was evident during an encounter at the luminous hole, where he landed with a bone-shaking roar, instilling fear in the party. Draz interpreted the creature's communication and confirmed it did not harbor subterfuge. Valghast agreed to take the party down to meet Ygva when requested by Draz, who later confirmed Valghast's name and role, indicating he would remain in the area to assist the group with their travel needs.
Valghast has become a crucial link between the party and Ygva, the spectral entity guiding them during their journey beneath Grithmaar Deep. While the party ventures forth, he remains at the site, responsible for retrieving them if necessary. Ygva communicates with Sylvie through dreams, suggesting that Valghast may also have a connection to dream communication or guidance. His presence serves as a promise of assistance, especially as the party confirms their intentions to seek a great creature linked to the god Mollthain, believed to be responsible for the destruction of Jamal's home. Ygva acknowledges Valghast's role, reinforcing his importance in the party's overarching quest.
