(Core)

Your patron is a lord or lady of the fey, a creature of legend who holds secrets that were forgotten before the mortal races were born. This being's motivations are often inscrutable, and sometimes whimsical, and might involve a striving for greater magical power or the settling of age-old grudges. Beings of this sort include the Prince of Desires, The Gentleman, ~~The Petal Dragon~~, The Seelie King and others that may be revealed later..

Your patron is a powerful being of Celestia but usually not among the Pantheon You have bound yourself to an ancient empyrean, Seraph, Hym Singer, unicorn, or other entity that resides in the planes of everlasting bliss. Your pact with that being allows you to experience the barest touch of the holy light that illuminates the multiverse. Being connected to such power can cause changes to your behaviour and beliefs. You might find yourself driven to annihilate the undead, to defeat fiends, and to protect the innocent. At times, your heart might also be filled with a longing for the celestial realm of your patron, a desire to wander that paradise for the rest of your days. But you know that your mission is among mortals for now and that your pact binds you to bring light to the dark places of the world

Instead of a single patron, you’re beholden to a myriad of pacts and contracts with different magical creatures, drawing small fragments of power from each of them to form a coherent magical library. You might forge these pacts during a long journey, painstakingly searching for a number of patrons willing to work with one another, or multiple lesser entities might approach you after witnessing you fall out with your previous patron. Living up to the demands of multiple patrons can be taxing, and you might find yourself at the center of conflicting requests from many of them. Warlocks who manage to maintain these manyfold pacts often pit their patrons against one another, using their bickering rivalries as a way to force them to keep one another in check.

(3rd Party)

You can hear the breathing of the Prismatic Serpent that coils around the world. You feel the coldfire of its breath upon your flesh. You can taste the rime of the northern seas upon your lips. Long has Gormadraug slumbered, and long may it yet slumber before the world’s ending. Even if that day is far off, your patron grants you power on one condition: that you hasten that day’s arrival.
Nearly all Valikans have a healthy mistrust of magic, but the hierophants of Thrull despise you over all others. To them, you are a sign of the world’s approaching end, a weed in the garden of life that must be torn out by the root before it can go to seed. They preach that those who claim to hear the voice of Gormadraug are mad, that they only hear the corrupting voice of one of the Serpent’s panjaians—its elemental servitors—for the serpent could not possibly speak while it still slumbers. The truth likely matters little to you, for you are to be persecuted by the fearful and faithful regardless of who exactly speaks to you in whispers. You may not be an agent of evil, but your powers were still granted to you by the enemy of all Grarjord, and for that, you know that you must keep your power hidden.
