The Corridor (回廊, Kairō) is a location in Suikoden Tierkreis.
The Corridor is an infinite space where all the Gateways that traverse the Infinity connected. Within the Corridor, there were countless Gateways, each of which served as an entrance to one of the myriad worlds of the Infinity.
Wahie, one of the Starbearers in the Company, was in charge of managing the Corridor, sending his colleagues and welcoming visitors from other worlds. Following the defeat of the One King, the Gateways became unavailable for use, drastically reducing the number of visitors to the Corridor.
