The Eye, Opened

Secreted in some Makers' trove rests a gleaming white object shaped like a key—not any particular key, but something closer to the very idea of keyness. It hurts to look at directly and makes you piercingly aware of your own dying flesh. You do not unlock its mysteries so much as it unlocks you: master your fear enough to touch it, hold fast as it wracks your mind and soul, and endure weeks of migraines and flashes of color. What it grants is a mind's eye that sees minds and auras where matter goes dim, reshaping what you can learn when you Seek Insight.
