I think I might be able to help clear up a few of the questions surrounding the protection ritual:
1. I would imagine they would be somewhere in the Faldric Forest, as that is where we found the leaf of the greenest green, and it makes sense to have plants from the forest itself as reagents of sorts for the ritual created to protect it. Am I right in this, Elle?
2. When we went into the forest on the last market day, we were told that for one reason or another, Elle's days as the Chosen One are coming to an end, and this time around there needs to be a new Chosen One. Only a Mystic Wood Elf can be the Chosen One. It would be silly if, say, a dwarf were the Chosen One who protected the homelands of the Mystic Wood Elves, would it not? So, at the last market day, after leaving the forest, Eldandiril gathered all the Mystic Wood Elves present at the time to figure out who the next Chosen One will be. It does seem to be on a volunteer basis, but it MUST be a Mystic Wood Elf. All but one of the Mystics present were either not born Mystic Wood Elves(being born a Mystic Wood Elf seems to give one's spirit a closer connection to the Faldric Forest) or have some strange thing happening inside their body/spirit, and that one Mystic that seemed the most eligible was me. So, when we do enter the forest, please protect me in particular(and Eldandiril for that matter), as I'm not very strong. I'm an earth caster and an alchemist, so I will be able to heal you at least enough to get you back on your feet, and thanks to Elle's ongoing "earth sickness" as I've heard it called, she'll be able to heal our protectors as well.
3. Again, I believe this ritual is to be done only by Mystic Wood Elves. Elle is ideally going to start the ritual, since she's been the Chosen One up to this point and knows exactly what to do, but as she said, she's going to sit down with all the Mystic Wood Elves that show up and explain how the ritual is done, just in case something does happen to her.
4.Since Eldandiril is still the chosen one, she should be more than capable of allowing everyone into the forest. She did it last market day, there is no reason she should not be able to do it again.
5. Yes, that seems to be the case. I'm sure the Mystic Wood Elves will be grateful to all who help protect us while we perform the ritual.
I hope this information is helpful, I'll see you all tomorrow evening.
