Vasilius's Links
Vasilius is Tao's older sibling, and has taken somewhat of a parental role over him as they were abandoned by both of their biological mothers at a very young age. While Tao insists he doesn't need to be looked after and that he's just fine on his own, Vasilius still worries. There have been times when Tao hasn't come home at night as planned, and has later been found sleeping soundly by himself in the middle of a nearby forest (much to the relief of his frantic older brother.) This has caused Vas to overthink his role as a parental older sibling, and constantly be convinced that he's not doing a good enough job. When Tao was younger, Vasilius saved up and gifted him with a set of jingling holiday bells to affix to his antlers so that Vas could hear him better when he wandered - and while their effectiveness in this area was always debatable, Tao still wears the very same bells to this day.
Vasilius and Tao's only known blood-related family member is Mona, who is their half-sister. As Mona was raised in an entirely separate situation from Vasilius and Tao, Mona was given far more opportunities to get ahead in life by means of a family wealth that her two brothers simply never had. When they are together, Vasilius will always try to be civil and kind to Mona, but his deep envy of her privilege (and bitterness toward their mutual estranged mother) tends to get in the way more often than not. As she and Tao get along just fine in contrast, Mona doesn't seem to understand why Vasilius can have such a temper toward her, and their relationship has always been strained because of this.
