Voice

"' FIRE MEETS WATER, EARTH AND AIR COLLIDE. A FLOOD, A BLAZE, A QUAKE, A TEMPEST WILL RATTLE YOUR BONES AND DISORIENT YOUR MIND. THE TIME OF RECKONING HAS COME AND WILL DESTROY ALL YOU KNOW UNLESS YOU BURY WHAT HAS LIVED.'"As Sacramentum, they appear mostly as a skinny pure-black cat with eyes that change colours, rotating between gold to purple to blue, with a long thin tail. They appear to be apprentice-aged, but have a very deep voice

As Voice, they appear as a group of cats shrouded in darkness with glowing eyes, all speaking in unison with their voices blended together.

Personality
Voice speaks in short sentences that leave you thinking, and acts in a manner unlike most cats. They seem shy around newcomers, and will not speak unless they are directly spoken to. They also pause quite often, using ellipsis's ('...') in most of their replies.

On Voice's blog they speak in a more refined manner, and most of their posts can be read with a sense of neutrality about them, but some certain posts seem to appear angry or wistful.

Voice appears to not anger easily, but they describe themselves to have a nasty temper when angered, and that many things can be committed by their hand if worked into a rage.

They also work as a cryptic prophecy giver, supplying the cats with odd messages and puzzles that they must figure out. They seem to enjoy watching both the characters and the members figure out what they mean.

Extra
They occasionally come online and speak in the discord, usually to supply hints to the lore of the story and to RP "Sacramentum". Voice even has a blog where they post the occasional hint or two, Visions of a Voice on Tumblr.

Voice is speculated to have been once living, and to have done harm to another to land them in what essentially is, purgatory. More hints we know for sure of Voice is that
 * They were once an 'apprentice' of sorts under someone besides the clan cats.
 * Knows roughly of where Grasspaw, Greypaw, and Shellpaw are. (Told us to check the Eastern winds.)
 * They were named 'Darkpaw' when still alive.
 * Killed Mistpelt, Frostpaw's father in rage over the other apprentice's death.
