Wheiskaet is an former captain of the Company of Heroes, where he defeated Titan and Leviathan. Because of his injuries during the fight against the Titan, Wheiskaet had to withdraw from the battlefield. When his company was disbanded, he and the rest of his men became guards for Gegeruju, a wealthy merchant who owns the beaches of Bloodshore.
In the absence of the Company of Heroes, the Maelstrom asked the Scions of the Seventh Dawn to deal with the Titan. Y'shtola and the Warrior of Light searched former Company members for information to infiltrate O'Ghomoro. They meet Wheiskaet who did not trust that the Scions had the ability to take on the primal and refused to divulge any information before they proved their worth.
Wheiskaet and his former comrades instructed the Warrior of Light to prepare a banquet. Once done, Wheiskaet revealed the banquet was an excuse for his comrades to assess their worthiness to face Titan. The five members of the Company of Heroes agreed that Warrior of Light had the qualities necessary to defeat the Lord of Crags. With the approval of his companions, Riol Forrest revealed the Company of Heroes had reached the heart of the O'Ghomoro mines using a beastman's aetheryte.
Wheiskaet supports his former companion Curious Gorge and helps his brother Broken Mountain in his recovery at Camp Bronze Lake. Wheiskaet encourages Broken Mountain to continue studying the techniques of the legendary Mythril Heart and asks the Warrior of Light to find some proof of Mythril Heart's existence.
Wheiskaet asks to Broken Mountain, Curious Gorge and the Warrior of Light to assist the Maelstrom in various operations against the beastmen at La Noscea. Eventually Wheiskaet decides to put his injuries aside and join the decisive battle against the sahagins at Camp Skull Valley. Storm Marshal Eynzahr Slafyrsyn himself joins the battle and witnesses the strength of the Roegadyn brothers and after the battle requests that they teach the novice members of the Maelstrom.
