Moonlight Siphon Vine

A fang-toothed vine, sharp and hungry, curls around an ancient undead oak like a predator in the dark. It doesn't hunt with claws, but with sips of moonlight, slowly drawing the pale glow from the tree's hollow heart. You'd use 🪷🌕 to describe something mystical and parasitic all at oncelike magic with a side of hunger.
