The Curator

Your patron is a mysterious cloaked figure known only as the Curator. Some claim the Curator is a forgotten, ancient god of knowledge. Others claim your patron is a demon, masquerading as something greater, and others yet still point to the Archfey as an origin for this mysterious figure. Most have never even heard of the Curator at all. You know the truth, however - what your patron is doesn't matter, only the Collection. The Collection is a demiplane on which the Curator resides, which all warlocks of this subclass can access, and it stores more information than any place that has ever or will ever exist. Your role as a warlock of this strange, silent librarian is simply to add to the Collection any new information you uncover throughout your travels, no matter how trivial it may appear.

Silence is Golden

Starting at 1st level, you share your patron’s ability to communicate and use magic without sound. You are able to cast spells with a verbal component without meeting this requirement, and spells that ordinarily produce sound only do so for you if it is necessary to their function.

Eerie Presence

Starting at 6th level, you can use a bonus action to cause every neutral or unfriendly creature in a 10-foot cube around you to make a Wisdom saving throw against your warlock spell save DC. The creatures that fail their saving throw all take psychic or necrotic damage (your choice) equal to 1d6 + Intelligence modifier + Charisma modifier.

At the 9th, 13th, 16th and 19th levels add 1d6 to the total damage dealt. Once you use this feature, you cannot use it again until you finish a short or long rest.

Keeper of the Arcane

Beginning at 10th level, your patron gifts you the understanding of powerful arcane secrets beyond ordinary mortal comprehension. This knowledge gives you a strange mental fortitude, allowing you to resist those who seek to deceive or manipulate you through any means.

You have advantage on all checks and saving throws against being persuaded, frightened, charmed or deceived. You have resistance to psychic damage, and you also become immune to the modify memory spell.

The Fates Themselves

At 14th level, you gain the ability to consult your patron directly, accessing the Collection in its entirety as an action in order to force the best result on any attack roll or skill check made by you or your allies. With the collective understanding of every being in the universe at your disposal, you can use this to achieve feats otherwise impossible. After all, even the fates themselves are no match for the mind of the Curator.

You must complete a long rest before you can use this feature again.
