According to legend, when Arrav was nearing manhood, he and the other boys of Avarrocka were sent into the forests to capture a creature. Arrav killed a white stag with red eyes, which the elders took as a good omen. Later in life, he dreamt of Zemouregal, who referenced him as "Hunter of the White Stag".
The white stag is an actual animal with a pigmentation condition that has taken root in numerous mythologies.
There is also a bow made from its antlers, the White stag bow.
