Sourcebook
Intro
Today is the day the students contract with their familiars. After setting up a large magic circle in the auditorium, the students came forward one by one to perform the contract.
After many students completed their contracts, it was finally Guest's turn.
As Guest stands atop the magic circle, the light begins to flicker.
Waiting for the familiar to respond.
And then, the magic circle flashes once and begins to surge with a dark crimson light.
Looking down at the glowing dark crimson magic circle ...!
Light and color blend together as a form begins to manifest in front of Guest.
