"Deep be roots, sturdy be limbs, tough be fibers of bark and heartwood.... but, mortal, before the winds of death, you cannot stand."
Ghosts are undead enemies that are encountered on the third level of Battlespire, which takes place in the Soul Cairn. They are referred to in religious texts and in dialogue as Mistmen. They deal moderate damage in melee, but have low hit points and are not difficult to defeat in melee or at a range. They will speak to you, but probably will not offer useful information and will try to attack you.

I naturally assume, you being undead and all, that you are suffering terrible anguish and torment. Aren't you? You sure don't seem all that miserable to me.
I abjure thee, spawn from beyond the grave! Abomination! Unholy specter! In the name of all that is good and just, I revile thee, and pray for thy destruction!
