Liliani wields the vethr, controlling and manipulating the storms and clouds of rain, wind, sleet, and snow. His powers are complemented by his wife Tijana: his rain holds power over her pyromania, his wind works in parallel with her blaze, and her blaze holds power over his ice. This relationship is also symbolic of their marriage as a whole.
Although matching his brother Hallr's stocky build, Liliani is a bit shorter and less imposing than his brother, and his hair is a much brighter red. He often wears a dark grey to complement his eyes and create a mask of seriousness; however, just as he can never hide his bright red hair, he never completely succeeds in hiding his outgoing and kind personality.
