At the back of the book there is an index. The top of the index reads,
Index
This is a very bad index and I'm sorry about that.
It's better than that introduction makes it sound, but definitely pretty bad, including having some entries squeezed in between other entries after the fact, some out of order because there wasn't enough room in the right spot.
Using the index, Maya can navigate to such pages as,
Plants
Gutberry: Fat red berries. Makes a decent meal if you can't get a better one. Stew with a pinch of smokereed to improve the flavour. If you let the berries spoil, they stink like you wouldn't believe.
Phoenix's Kiss: Warm orange petals. Alchemists and wandcrafters use this for a basic fire element.
Ice flower: Icy flowers. Water element. I'm told you can also make glass with it, somehow.
Wyrmweed: Big green leaves. I'm told it looks like seaweed. Nature element.
Smokereed: Long yellow flowers that make smoke in the daytime. Air element.
Sporeshroom: Luminous purple mushroom. Harvest at night, avoid during the day. It has uses but I don't know what they are.
Bitterrice: A bitter grain. Grows well in a garden. Tastes bad.
Honeydrop: Hexagonal golden pods. Sweetens any meal, and good in a healing potion too.
Voidcap: Likes dark enclosed spaces aboveground. Useful but annoying. Dark element.
Mandrake: I think it's pink?
Runewood: A tree that glows green. I've never seen one. The wood is useful for crafting and construction.
Trapdoor Vine: Eats people. If you catch one, pick its teeth out, they're good for something.
Unstable Anemone: I don't know what it looks like or what's unstable about it.
Crabbage, Jumping Nut: Better crops than bitterrice, I'm told.
Fractal Mold: ???
Though she may also take note of, for example,
The Underschool
I'm told the passages beneath the Mana Font were once used to hold obscure ritual equipment, but that was before the fog. Right now, I don't know what's down there but I know that it frightens me.
The page on wandcrafting generally corroborates the plant list's elemental associations; it also suggests using a chip of stone as the elemental source for an Earth wand, a bit of copper or iron for Lightning, and using animal sinew instead of Voidcap for a less powerful but more readily available source of Dark.
