Spoilers for Sethian are many and unmarked. There’s one in the second sentence.
Imagine talking to a chatbot, with a writing system you barely recognise, and with all the linguistic capability of a three-year-old. Now imagine that the conversation is on religion and philosophy, and you’ve got the central conceit of Sethian.
