Before, the Power Tribe was attacked by a cannibal Super Tribe, which captured many clansmen as reserve food, leading to the decline of the Power Tribe. As for the fate of those captured clansmen, it goes without saying—they either became reserve food for the cold or hot seasons or, like now, were brought by the Cannibal Clan to the Mutual Market, becoming goods on sale.
The Cannibal Tribe is a cruel yet powerful tribe because it almost never starves. This is due to their hunting range, which includes not only beasts but also humans. Typically, their hunts prioritize beasts, as beast meat is abundant.
Only before the cold and hot seasons arrive does the Cannibal Tribe launch full-scale attacks on smaller tribes, taking their people as reserve food. Besides this occasion, they only capture people before starting the Mutual Market, and those captured become the Cannibal Tribe's live meat for trading at the market.
