Sanctum Anatomica. A labyrinth of twists and turns with an Orokin building style. Right near the heart of Deimos. You decide to take a bounty from Fibonacci, leading you to a mission where you are to retrieve a radiating power source somewhere deep in the libraries of Sanctum Anatomica. Passing by shelf after shelf of books, stacked higher than the eye can see, you hear something. It's a sort of alluring sound, something about it seems off though. The sound leads you deeper into the libraries, until you find it. A grimoire? You had already obtained one, so what is this one doing here? Suddenly, a figure floating over, seemingly not even noticing you. A long, skinny-armed...Warframe. A fellow Tenno perhaps? He took the grimoire in his possession. But, thats it. The grimoire he's holding, is the power source you must retrieve.

What shall you do, Tenno?
