The Wanderers (ランブル族, Ranburu-zoku, Rumble people), their full title in Japanese being the Rumble Tumble (ランブルタンブル, Ranburutanburu), are a race that appears in Suikoden Tierkreis and Genso Suikoden Tierkreis Hoshikuzu no Shiro. They are wandering merchants with the ability to traverse the Infinity.
The Wanderers are known mainly for two things; their large glasses and their larger wallets. Almost all Wanderers are engaged in some sort of entrepreneurial business and do not have a fixed home, preferring instead to travel the land in small groups. They were also able to utilize Gateways and travel to other worlds, expanding their businesses further.
In truth, the Wanderers are a race which originate from another world, brought to their current location with the Chronicle of Endless Travels when their world was absorbed by the One King. The world which was fused after theirs apparently overwrote their own remnant, but as by then the Wanderers had already mostly dispersed, it appears that there were few casualties.
Following the fall of the One King, the ability of the Wanderers to travel the Infinity stopped, his presence throughout the Infinity being what linked the million worlds together.
