/* Quick note:
 * This looks entirely redundant and silly, I agree. However
 * this is because the source does more or less the same thing.
 * At compile time, it creates and stores in memory what are the
 * equivalent of structs (or maybe tuples), and then at run time
 * when creating a room, it makes room specific versions that can
 * be changed. So essentially it creates two RAM structs and then
 * treats the first as ROM. As such, that's what I'm doing here.
 * The 'Story' structs are ROM, the 'Room' structs are RAM. There
 * are also slight differences, like how the room Flame has a reference
 * to the Cyc it is using. Although again the Story ones are ram
 * and could do this too.
