one thing i really appreciate about the locked tomb is how it's made clear in every single setting that every single character is under constant exposure to mold poisoning. like. canaan house? unbelievable amounts of mold. the mithraem? they're eating "necromantically preserved food," you cannot convince me there's no mold. i've just started nona the ninth and one of the first things they establish is that there's black mold in the apartment. it explains everything that happens in this series actually. every single mind-numbingly stupid or crazy decision that everyone has made is, quite simply, just the mold talking.
