Shiroiwa (Japanese for "Castle Rock") is the city from which Class 2-B hails. While a far cry from the metropolis of Tokyo, it is still large enough to support a relatively diverse array of activities, and is markedly more urban than rural. Though not the city situated across they water from the island, it is remarkably similar in size, and the nearby civilization may provoke memories, especially at night when the lights shine. While this forum is named for Shiroiwa for thematic reasons, memories set elsewhere are also allowed. Characters may be in one active memory thread at a time, though may also have one-shots or solo threads as desired without counting against the cap.
