Five Pebbles (character)

Five Pebbles is the iterator met at the heart of the Five Pebbles supercomputer. He is one of the two iterators you can meet in the game, the other being an ailing Big Sister Moon.

Five Pebbles is nonaggressive to the slugcat. He gives you the communications ability and, once he can talk to you, gives you directions to escape the facility and ultimately complete the game.

Backstory (spoilers)
Five Pebbles is corrupt and is the cause of the collapse of the Looks to the Moon facility.

The lore behind the iterators.

Trivia

 * Five pebbles can move around his chamber while Big Siter Moon can't, because of the damage she has sustained.
 * He has a cloak... yes!
 * Five Pebbles reveals that his hardware is succumbing to damage -- and by extension the other remaining iterators are probably in similar states, apart from Moon, who is worse off.
