[Morsul the Dark]

let us return for a moment to the the good ol' days of creation a good friend Yavanna created ents (by my understanding) by putting spirits into trees to protect them from the dwarves... what if one of these spirits as apposed to becoming treeish became more active especially when seeing a certain miss goldberry He may have originally been an ent spirit that escaped his tree(who became souless and evil (our Mr. Old Man Willow))
