Vlau, mother to Cheval, resided within Hakum Village, a secluded community where Riders and monsters coexisted in secrecy. Her death came during an attack by a Nargacuga corrupted by the Black Blight, a pivotal tragedy that shattered Cheval emotionally and fundamentally shaped his character arc. The Blighted monster's rampage through the village resulted in her demise.

Cheval inherited Vlau's necklace following her death. This object became a tragic keepsake, a constant symbol of his grief and the fuel for his consuming obsession with vengeance. The necklace's later destruction marked Cheval's full descent into ruthlessness, abandoning his earlier reservations about destroying Blighted monsters and cementing his commitment to revenge.

Her background remains unexplored beyond her role as Cheval's mother and a Hakum Village resident. Her narrative function centers solely on catalyzing Cheval's transformation from a gentle boy into a ruthless avenger fixated on destroying the Black Blight and its monsters, driving his conflicts with others.

Vlau's legacy permeates Cheval's development as he grapples with misplaced retribution towards monsters, eventually reconciling his trauma years later. By *Monster Hunter Stories 2: Wings of Ruin*, Cheval has regained his gentler nature, though hardened by his loss, and actively mentors younger Riders to prevent them from following his destructive path.
