Quill

The Quill is an artifact of the Thirteen and one of the most powerful items in creations. Though it appears no more than a simple writing stylus scaled to Transformer hands, it has the power to change the future of the Universe itself. When used together with the Covenant of Primus, the Quill has a limited ability to literally write new events into the future.

This is not a power to be used lightly, and the future is a strange and mutable thing, so the changes written by the Quill do not always last. Still, it is an object of immense potency that must be guarded carefully, something Alpha Trion sees to by keeping it secret even from his closest allies.

The young librarian Orion Pax presumed Alpha Trion had simply become eccentric because he used a stylus and book as his interface.
