Rattle is a pudgy, quiet man who lives in Craddle (though he claims that he does not really belong there). He has thinning, medium-length brown hair, visible bruises and scars on his arms, and he seems to walk with a slight limp.

Rattle is a criminal condemned to live out the rest of his life in the Bandit Lands. While it is unclear what Rattle has done exactly to be so condemned, he lives in Cradle, a camp that is largely filled with those who committed crimes against children. Rattle claims that he does not belong in Cradle, or in the Bandit Lands at all, though he is quite demure about his innocence unless pressed. Rattle wants to help those who want to make the Bandit Lands a better place for others, and the Bandit King seems sympathetic to his plight.
 
Rattle bears scars and bruises from his time in the Bandit Lands, though he will not say whether they came from a harsh life in Cradle, or if those in other camps have wounded him based on his known affiliation with the Cradle.
