Vine

Vine is a Lich demon and King of Gehinnom, one of the nine kingdoms of Shadowfell. He is considered to be the trickiest and deadliest of the demons.

Physical appearance
Vine's initial form is that of a lion riding atop a black horse.

In his human form, Vine appears as a slender, winged man with shoulder-length platinum blond hair.

In his true form, Vine appears as a vague, tall form with a barbed tail, horns, claws, and fangs. Regardless of form, he always carries a golden staff. The staff is truly a vicious mace with the ability to entrap souls.

Etymology
Vine appears to derive from Latin "vinea", meaning "vine", which is also the name given to an ancient war machine made of wood and covered with leather and branches, used to overthrow walls.
