The Lost Library of The Forgotten King

In the space between spaces, where realities fade into each other, where planes and worlds go to die, lies The Lost Library of The Forgotten King. Watched over by the many-armed Librarians in their golden masks, it is a place full of all of the secrets and knowledge that have been lost to time.

Upon forging a pact, you are bound as an Archivist of The Lost Library.  Many Archivists slave their entire life away in service to their master, ever hungry for knowledge, especially that which is hidden or forgotten.

Wretched Gaze

The Library of The Forgotten King is a place of knowledge, and to aid you in the pursuit of knowledge, it has blessed you with greater perceptive abilities as well as an ability to tell truth from falsity.

At 1st level, you gain proficiency in Wisdom (Insight) and Wisdom (Perception) as well as the ability to cast Zone of Truth three times per day.

Hidden Knowledge

You have access to The Library of The Forgotten King, where secrets and mysteries lie hidden to all but those who have access to the vast halls. You gain your Charisma modifier on any intelligence checks.

Aspect of the Librarian

Yhe Librarians of The Lost Library are tireless beings that peruse the countless aisles and do the bidding of the Library itself: compiling, enscribing, and filing.  At 6th level, your physical form begins to change to reflect the Library's influence.  For some, their skin pales to the color of ancient parchment, while others find their faces become golden like the masks of the Librarians, some find themselves covered in lines of script in an unknown language, and it is even said that some find themselves with extra arms.  Alongside these physical changes, there are also many unseen benefits.

You gain a resistance to fire and psychic damage.  In addition, you no longer need to eat, drink, or sleep, though you do require periods of rest to recover from any cases of exhaustion.

Open Door Policy

At 10th level,, you gain the ability to open a back door into the library itself. You can bring 1 person with you without any trouble. You can bring up to five people with you, but they must succeed on a Constitution save equal to your spell save DC. You can attempt to bring up to ten individuals, but they will be required to make the same save with disadvantage.

Anyone who fails this save is pulled from you and successfully into the space between planes and can only be retrieved by a Wish spell.

Those who succeed on the save find themselves in The Lost Library of The Forgotten King. While here, you are immune to any methods of detection or communication from outside sources. You also do not need to eat, drink, or sleep while in the Library. While in The Library, you have advantage onany intelligence-based checks due to the large numbers of books at hand that cover almost every topic imaginable.

You can use this feature once every long rest.

Piercing the Brain

At 14th level, you gain the ability to tear at the mind of a creature you see, gaining access to it's memories and knowledge.

As an action, pick a creature that you can see. They are instantly wreathed in a golden light which seems to eat at them like tongues of flame. They take 8d6 psychic damage, and make a wisdom saving through against your Spell Save DC. On a failed save, you may chose one of the additional effects:

- Terrorize: You reach deep into the mind of the target and force it to live a moment of truth or revelation that is truly terrifying.  Perhaps it is a suppressed memory. Perhaps it is something they did not know which shatters a strongly held belief. Whatever the case, the target takes an additional 4d12 psychic damage.

- Spell Steal: If the target knows spells of a level of which you can cast using your pact spell slots, you can choose to temporarily gain the knowledge of how to cast one of the applicable spells. This spell can be from any class' spell list, and you can cast it using your warlock pact spell slots. You retain the knowledge of this spell until the end of your next long rest.

- Thought Scan: You force the creature to relive a specific event from its past. If you know of a specific event, you can specify the moment you wish to see. If not, you see the past 24 hours of the creature's life play out beat by beat exactly how it remembers it. If the creature's memory of the event you witness is effected by a magical effect such as modify memory or similar, you will sense that the memory has been altered, but do not see the original version. As you search the creature's memories in this way, it relives the memories with you, and after you finish shifting through its mind, it will know exactly what you saw from its mind and that you now know it.

You can use this feature once per long rest.
