Hollow

Hollows are a race of undead from the Dark Souls series, a set of creatures who have died so many times, their memories have simply rotted away. They seek out soul-bearing creatures, and come in three varieties: Normal, Marked, and Lord.

Regular
Common Hollows are very simple creatures, very slow and feeble, but are ravenous and will attack anything in possession of even a single soul. They are capable of wielding basic weaponry, straight swords, crossbows, shields, daggers, and bastard swords.

Marked
Hollows given the curse of bearing the Darksign, a mark that gives the Hollows a little of their memories back. This allows them to access some of their previous memories, using a humanity (or human effigy). These creatures are capable of wielding any weapon, from a lowly dagger to the mightiest swords known to man.

Lords
These are the chieftains of the undead, who wield souls far beyond the power of a regular Hollow, or were on their way to becoming a Monarch. Known examples include:
 * King Vendrick
 * Lord Gwyn
 * The Nameless King (King of Storms before his dragon is killed)
 * Manus
 * Gravlord Nito
 * The Soul of Cinder has an unkindled hollow appearance

Exceptions
The following creatures are exceptions to the normal formula of Hollows.
 * Havel the Rock
 * The Gyrm
 * Knight Artorias
 * The Phantoms in every Souls game
 * The Spirits which roamed in Demon's Souls
