Currently it's mostly bullet points.
-Reintroduce herself, introduce her mom
-Say she's going to talk about what shoggoths do for castes
-Background: shoggoths live a really really long time, and might not die of old age
-Earth shoggoths currently don't have formal castes, but there's a caste-like thing with age
-The oldest shoggoths, who were old enough to have fought in the first war the shoggoths had, when they were rebelling against their creators, are like the greys. They mostly protect the communities from predators and sometimes scare off aggressive neighbors.
-The second oldest shoggoths have wisdom jobs. That's most blue jobs - stuff like mediating, or leading, or judging cases, where being really old and experienced helps a lot.
-The shoggoths who're old but not ancient have knowledge jobs. That's most green and yellow jobs - stuff that benefits from having lived a long time, but where you don't get a ton of extra benefit over the millennia. History, science, really hard art forms. Fun fact: most shoggoths have kids while they're in a knowledge job.
-Shoggoths who're new adults have energy jobs. That's most purple and orange jobs - stuff that it's really good to be young and energetic for. Building, caring for the sick, teaching.
-There's no hard and fast line between the castes, and if you're really talented in one area you can skip around. Mom's really young, for instance, but she has a good memory and is curious and wanted to do a job not a lot of people are doing. She's a cultural anthropologist, specializing in one of the shoggoths' same-planet neighbors, humans.
-Some jobs get sorted differently than Amentans do things, too. Bright gave herself blue hair because she wants to be a diplomat, which is an energy job, because interacting a lot with strangers is hard for older shoggoths.
