A few years ago during an attack during an attack on Beacon Academy and Vale by a group of demonic entities including their leader and king named Onaga or as he's preferably known as Knightmare

A young huntress in training by the name of Kisara Ventura was murdered during the attack in as she was trying to protect her friends and teammates from tyrant knight king before her friends from Team Sigma,Team RWBY and Team JNPR would have made proper burial and grave for her within the school after the ambush and before going after Knightmare in a attempt to defeat him and seal him away

However,4 years later,The tyrant would have brought back into the world at this same time there were rumors of the young huntress who gave her life to protect her loved ones from him somehow also returning from the land of the dead but now back in the world of the living but appears to have more of the features of wolf now even turing into one during the nighttime

While you and possibly a few others were searching around to find out if this was actually this was true,A giant creature would have began to materialize from some of the water surrounding the area before it started searching within the area

(You are ethier aloud to know Kisara from during your character's time in Beacon and have been friends or has only heard of her and don't know her personally)

(You don't know how she was brought back to life or who did it and how she would have came in contact with an elemental spirit simliar to Phantom's wind spirit, Mokin,which looks like the picture below)
