The Ceaseless Watcher

Your pact with The Ceaseless Watcher is an oddity. The entity that you call your patron is known to be a more passive member of the non-gods from which mortals can borrow power, and it seldom communicates directly with the material plane to express wishes and motivations even to its devoted followers. Seemingly, for centuries, it has been largely content to merely watching and only influencing cause-causality to a limited degree. As such, conflicting interpretations of it’s will remains among its followers.
‘It Watches’ might have been completely unknown on the mortal plane, if not for the founding of the Videre Archives and the efforts of the order of expositors trained there, carrying symbols of ‘the eye of knowledge’ and aiming to fulfill its wishes, as interpreted largely by themselves or the archive elders. 
Often followed by an overpowering sense of being watched, ‘The Eye’ appears to offer its gifts in exchange for various types of knowledge, as offered to it through the experiences of its followers, or secured in written records in the Videre Archives. 
As such, after being trained in the Videre Archives, archivists and expositors often go out into the world attempting to gain the favor of ‘The Eye’ by seeking out all that is hidden or forgotten, and securing it for the archives, with little regard to the societal consequences.
However, it is as of yet unclear if ‘The Eye’ feeds only on the knowledge presented to it, or if it is sustained also by the turmoil and fear which precede and follow its discovery.

To See to Know

Beginning at 1st level The Eye watches through yours giving you advantage on any investigation checks and allowing you to add your proficiency bonus to any perception checks. 

For Me to Know

Beginning at 6th level The Eye has seen your value to its purpose. You are now able to cast Identify and Detect Magic without using a spell slot. You can also add your proficiency modifier to any Insight checks as The Ceaseless Watcher whispers to you how to get the knowledge you seek from others.

Eye Never Closing

At 10th level your link with The Eye has grown so deep as to make a third eye appear on you. The eye never blinks and provides you with a passive perception bonus of +10.
The eye is also able to cast 5 spells of up to 3rd level from your expanded spell list without spending your spell slots. This however drains the eye and it closes, removing your passive perception bonus.
The eye remains closed for 1d6 hours.

In The Ceaseless Watchers Sight

Beginning at 14th level your third eye grows in power. The eye gains the ability to cast any of the spells in the expanded spell list and the muber of times it can do this is now equal to your proficiency bonus.
The eye is now also able to freeze a target within sight, forcing the target to give up any information you might want - doing this drains the eye, closing it for 1d8 hours.
