Outsiders.
Having your mother join your souls in a pathway of communication will mean sharing all of your memories with her again, which could be dangerous.
Some outsiders grow in strength and spread like a plague through memories. As more and more people acknowledge their existence, the more Mother Earth veil weakens around them, giving them agency and the possibility to feed. Or it put a target on their backs.

You've never studied any entity like this. A singing tree-like freak of flesh with six arms and just as many mouths? Never. What in Father Sky's knowledge could it be?

This is a very important choice.
>Agree with sharing what you've learned with your mother and father. Leave your friends out of this, for now.
>It is better if everyone understands they've missed an entire week of life. Share this new with everyone.
+With Augustine?
>Keep this entity's existence to yourself for now. Until you get proper information... it'll be better to be subtle.
>Free
Say hello to the main villain. Rey is such a good person that it got revealed early.

For one moment that feels far too long, the noises outside keep you rooted to the door. Constant wet thumps, roars of passion, and that pressure of activity almost narrow your vision to a fine point of darkness. But little Usha, crawling across your table with the total incomprehension of a newborn lamb, stirs your limbs into motion.

Mom's weapons, her magical arrows...

''Uu!?'' Your dear, tiny new friend protests angrily when you grab her and shove her into your pocket. You see blurs of movements from the windows, but you don't linger to observe; the lack of impact on the door gives you a little hope.
Seyraphal and Shigeko... They're strong. Good Mother, give them strength!

You nearly kick open your parent's door. Their room remained spartan; a bed big enough to accommodate them, two wardrobes put side by side, and your mother's workbench for fletching arrows, with a row of newly made healing potions in the center. Above the bed, resting on a shelf, was your father's dutiful work in opening a tiny pathway into Mother Earth's web; a shiny round distortion using a statue of the Good Mother as an anchor.

Father's Blood, thanks! Your mother's sword and her important Ironwood bow are next to the bed, and you nearly collide with the wall as you clap the leather belt holding the blade holster and quiver on your waist, immediately extracting one arrow to keep it in the same hand holding your new bow. Your parents also have two windows: the north one gives you a bad angle of Seyraphal battlefield, and only the mutilated remains of a walking canine corpse that found brutal peace hint at her struggles.
What-what's that!?
The eastern window covers the door of your home bathroom, and there you catch a glimpse of a dark humanoid figure closing the door.

''Ironwood arrow Iron arrows!''
Not under the bed, Mom would want to find them in a crisis. You nearly drop on your face to look under the wardrobes.
Good! Canaan hasn't constructed a proper hiding place yet. Another small quiver holds the handful of precious Ironwood arrows, trophies of her time in the Rangers of the Northern Watch, the order who safeguard the Allied Kingdoms from Outsider incursion from the swamp.
Lightning one is safest in the house! The arrow itself is a piece of gray wood covered in runes without fletching and a pointed end carved into the wood. Wands and projectiles both, treating them like normal arrows is a deadly mistake.
Activating it means touching your Focii.
