"Vossler York Azelas (ウォースラ・ヨーク・アズラス Wōsura Yōku Azurasu), a 38 year-old Hume, is a former Dalmascan Knight and a close colleague of Basch. Vossler fought alongside Basch, during the counter-attack at Nalbina Fortress. Like Reks, he too was tricked into thinking Basch was responsible for killing King Raminas. After the battle, he fled underground, and joined the Resistance, alongside Princess Ashe. For the next two years, he protected the Princess, as well as trying to restore their lost Kingdom."
