Finishing up the final entry to the Aeon Student Guide (which will be included in the stat screen next update). The above photo is an extremely rough draft, but overall the Student Guide is almost 4,000 words of pure lore dumping.
Completely optional lore dumping, mind you!
There's some reactivity if you read over it before Rosy's class, but the game is fully playable and comprehensible regardless of whether or not you choose to read this extra material (I didn't include it in the first draft in order to make sure that the story didn't rely on it). There are a few context clues that may help you figure out MB's plot, but they'll also in the main text so are more reinforcement than revelations. Mostly, the Student Guide just gives you a deeper understanding of the world and may be helpful as a roleplay aide when deciding your Button's opinions.
