THE HARROWED REALM
A Varisian bard named Sonnorae Imlios created the Harrowed Realm as her own demiplane where she could live forever. She crafted the demiplane out of a portion of the Dimension of Dreams, using her own harrow deck, the Deck of Harrowed Tales, as a magical focus to build the realm upon. The magic of the Harrowed Realm eventually breathed life into the characters of Sonnorae’s harrow deck, and these immortal creatures became known as the storykin. A group of eight storykin called the Conspirators grew tired of playing their preordained roles and, in a violent uprising, killed and consumed Sonnorae. The Conspirators now rule the Harrowed Realm, each with their own kingdom and a portion of Sonnorae’s power. The Conspirator Zassrion, a blue dragon, controls Sonnorae’s harrow deck and uses it to corrupt those who happen upon the deck on Golarion.

The storykin are avatars of the harrow deck’s cards, brought to life through the power of the Harrowed Realm. Most of the storykin are limited in their autonomy, spending their lives acting out the roles in the stories they originated from. The form and alignment of a storykin eidolon is dependent on the harrow card the eidolon is based on. You can reference an actual harrow deck for these eidolons (harrow decks are available at paizo.com or at many gaming stores, and pictures of the harrow cards can be found in Pathfinder Player Companion: The Harrow Handbook), but you can also simulate the suit and alignment of an eidolon from a harrow deck as detailed on page 293 of Pathfinder Campaign Setting: The Inner Sea World Guide.
Alignment: Varies.
Base Form: Bipedal (limbs [arms], limbs [legs], slam), quadruped (limbs [legs, 2], slam), or serpentine (bite, grab [tail slap], tail, tail slap).
Base Evolutions: The first time a summoner summons a storykin eidolon, he must select a specific harrow card, typically one that features a creature, such as the Paladin, the Rabbit Prince, or the Tyrant. This choice determines the eidolon’s base form, alignment, and overall appearance, as the eidolon resembles the creature from the chosen card. Harrow cards without an obvious creature instead manifest as a generic humanoid creature made of colorful patchwork cloth. A storykin eidolon’s alignment matches the alignment of the chosen harrow card and still must be within one step of the summoner’s alignment. The suit of the chosen harrow card determines the abilities of the storykin eidolon as it evolves. When the summoner gains a level, he can choose a different harrow card and thus a different base form, alignment, and appearance.
At 1st level, a storykin eidolon gains the resistance (sonic) evolution. In addition, storykin eidolons of the suit of hammers and suit of shields gain a +2 bonus on Fortitude saving throws. Storykin eidolons of the suit of books and suit of keys gain a +2 bonus on Reflex saving throws. Storykin eidolons of the suit of crowns and suit of stars gain a +2 bonus on Will saving throws.
At 4th level, a storykin eidolon gains cold resistance 10 and electricity resistance 10.
At 8th level, a storykin eidolon gains the ability increase evolution, applied to the ability score corresponding to its harrow suit.
At 12th level, a storykin eidolon gains immunity to bleed, poison, and stun. It also gains DR 5/adamantine.
At 16th level, a storykin eidolon loses the resistance (sonic) evolution and instead gains the immunity (sonic) evolution. It also gains immunity to mind-affecting effects.
At 20th level, a storykin eidolon gains immunity to all types of ability damage and ability drain against the ability score corresponding to its harrow suit and immunity to energy drain. It also gains the ability increase evolution again, applied to the same ability score that was increased at 8th level.
