They are tiny people living in your house. The Solaam are the humans.
SPOILER SPOILER SPOILER SPOILER
There's a note that says something like "At night, when the solaam go above..." meaning when they go to the bedroom. The blue family got exiled Outside and came back with an army of ants or spiders. Solaam can step on them, and at some point there's a mention of a new solaam-family/clan that leaves food in a place they can access easily. To get at the new food supply, the people learned to ride mascet (mice or rats) and use them as pack animals. But then a large, furry creature appeared, apparently brought in by the Solaam, that loves to eat mascet! The family got a cat and it messed up the logistics in this tiny kingdom.
