// Regarding Arbiter Vel //
// I’ve actually already got a headcanon for Arbiter Vel.
In my mind, Arbiter Vel is a version of Vel after his final encounter with Zilean, the Chronokeeper. It is already stated in the lore that Vel is constantly searching for Zilean to learn of his secrets of Chronology.
To me, Arbiter Vel’s new ethereal sounding voice lines, coupled with the fact that his appendages are made of pure energy, lead me to believe that this is Vel where he has acquired Zilean’s Chronology knowledge, and used it to become an omniscient being, all-knowing of everything in the past, present, and future.
Or I could be wrong, but that’s just my two cents on it. //
