There's also a doll on the Court side of the tree. Maybe the doll that Reynard killed that I can't remember the name of will make a return.
Also, a LOT of alchemy symbols. I'm going to go dig through some stuff to find some of the more philosophical meanings of them and make a list here.
Alright, first, at the top of the tree is Bismuth. There is, of course, the whole "Grown from the Bismuth Crystal" thing about the Court. Aside from that, I can't find much relevant information, other than that it's supposed to be very toxic, which might tie in to the whole Court vs. Forest thing.
On the left branch just under Bismuth is gold. Strangely enough, gold is ruled by the Sun in alchemy, and it's opposite of the sun. I don't recognize the crown symbol opposite gold. I also don't recognize the symbol below gold. The symbol below the crown appears to be a combination of two mercury/quicksilver symbols. This gives another hint towards the doll character, as that's the symbol that was on her.
The moon represents silver, though it might also just be a moon.
Then there's the two triangles. The top, facing up, is the symbol for fire, while the bottom is the symbol for water. Strangely, in the top right corner of the bottom triangle, there's another fire symbol. The top left has no meaning that I can find. The bottom is mercury/quicksilver.
The top corner of the top triangle appears to be a sightly modified version of the symbol for tin. The I or the other symbol I can't find a meaning for.
Also, the doll under the Court side of the tree has a symbol on it. I can't quite tell what it is, but I think it might be a slightly modified version of the sulfur symbol.
