Deep in the Royal Library is a book. A terrible book that is said to send whoever reads it mad. A book so dangerous that it has to be hidden away and secured with chains to prevent it from ever being opened.

A book which has just been accidently checked out by Spike on behalf of Twilight Sparkle.

The Star In Yellow is rising once more, and only Rainbow Dash and Spike can save Twilight before it's too late. Ideas live forever. Ponies do not.

This fic is loosely inspired by the 19th century story 'The King In Yellow'.

This, this is why I spend so much time in the archives, Twilight thought, holding a dusty old book close in her magic. Inside the book were a number of advanced spells, each one more interesting than the last in some sort of circular logic that Twilight could only assume went to infinity

Twilight galloped through the doors to her tower and leaped onto her favorite reading pillow on the balcony. She opened the book to the table of contents.

Oh my gosh! They’re all so interesting! Ooh, an age spell! That…might be a bit beyond me. But here right below it – a duplication spell!

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.
