[It's likely only a few people noticed, but about two weeks ago, Ayumu vanished completely from the village, along with all of his belongings. It's clear he went home, and that should have been the end of it.
But today.... Deep in Egypt... Deep in the depths of a pyramid is a treasure room with a fancy sarcophagus. It probably looks the same as most of the other pyramid treasure rooms, but this one is a bit different. If you get close enough, and make some noise.... it starts to shake. Like something is inside.
Any treasure hunters are welcome to investigate.
Later in the day, after that drama has unfolded and the sun has set enough for him to escape Egypt, Ayumu can be found wandering the rest of the village looking for his house. It's a pretty daunting prospect because there aren't any familiar landmarks anywhere. So, he can also be found trying to escape gangsters in Mobland or being chased by dire bears in the ice age (he really has no luck with animals.)]
