Trivia

 * Apparently just having a high Level is enough to make anyone desire challenging you in this world, regardless of the fact if your an active fighter or adventurer.
 * Azusa at this point is only known locally as a generous immortal witch who helps out with medicine.
 * Though after Azusa defeats Laika, everyone stops bothering her; plus everyone in Flatta would warn against angering Azusa.
 * Despite it being a BIG DEAL, the concept of levels never comes up again.
 * The adventurers and Laika arrive whenever Azusa is having a meal; befitting the old trope of "it never fails; [do something] and then [an interruption happens]"
 * Despite Laika bringing a small fortune with her, she largely only uses natural materials and nothing bought with the house construction.
 * Dragons retain their strength in human form; Laika carried house wall length logs without much effort.
 * Flatta treats Azusa as local hero/celebrity for her centuries of generous help.
 * For the exposition about Ernst, apparently no one has been trying to kill him for being a blannermouth; even Azusa, who has a violent temper when crossed bad enough (and THIS qualified). Even Natalie Jr. finds him distasteful for his inability to shut up.
 * As Laika is later shown to be honorable and a sweetheart, she was clearly bluffing when she claimed to be willing to rampage in Flatta to get Azusa to accept her challenge.
