"Thanks!"
Some talk with mom, and: "There's the Elder Things, or there used to be. They had an interplanetary empire and made a bunch of other species including the shoggoths to be their slaves, and they were jerks and got into fights with everyone they met, and then the shoggoths and a bunch of others rebelled and their civilization collapsed. We don't know if there's any more."
"The Yith also were fighting the Elder Things over Earth - a lot of people fought over Earth for a while - but they left when the planet got less habitable for a while."
"The Cthulhi also fought the Elder Things, but we dunno what happened to them."
"The Mi-Go are in the same solar system as Earth, and fought the Elder Things, but they don't like Earth 'cause the gravity's wrong or something. They have a really weird moral system and are sometimes jerks."
"The Flying Polyps also aren't from Earth, but we only heard of them from the Yith who were their enemies."
"The Lloiger are from another galaxy and we haven't heard from them in forever but they might be related to the Flying Polyps?"
"I think we met the Yaddithians like once? Dunno much about them."
"On Earth, there's humans, Deep Ones, White Apes, and shoggoths that me and mom know of, though there might be other small groups hiding. Shoggoths are actually on a lot of planets, but we lost contact with the other groups when the Elder Things closed the portals."
"Deep Ones are an amphibious people, and they're allies with the sea-shoggoths and some coastal humans."
"White Apes might technically be a human sub-species? They only live in a very few places though and we don't have much contact with them."
