???: A spirit trapped in grief and solemn purgatory, chained against the Forlorn Pillar. Three tolls the Bell of Mercy had to ring to redeem him from his chains. Upon that release he was to find his new path.
Eons went by it seemed. Memories, dreams and ghostly haunts of depraved spirits were his only company in the Grave Stone Fields of Memory. Then the Lord of Darkness gave him an option. He could continue to wander or become a being summonable by the mortal world.
Year 1805: He was given to Emily by a grim hound to create change in not just her mundane life but in the path that Eidolon was to follow. Upon his release he attacked the ones her heart distanced and saved her ally.
After assisting and watching over Emily, Fenrir made a friend in the emo, Eidolon. Though the spirit himself has no attachment to the finding of the Paladins (the point of the whole trip Emily was making with Lilla), when they did find them it was a surprise being they WERE Paladins. Once they returned to Emily's home she enlisted as clergy to escape Tina's retribution. Fenrir followed along like a good summonable spirit.
Year 1828: Emily dies and leaves Fenrir's Ring to Eidolon. The spirit informs his new master of the situation.
Year 1843: He assist Eidolon & Bale when they help the team going to Sardor Isle. He provides scouting information on the undead presence there and where the living hide behind the barrier.
Year 1853: When Kirin goes lusty-asault on Eidolon while on the ship, Fenrir has no way to get them clear except to pull them into his spirit world. As a result, they see the true version of Fenrir. Time passes differently there though so when they will come back out is anyone's guess.
Year 1854: In an attempt to help reform the madman, Eidolon extends a hand of friendship to Kirin - against Bale's better judgement. Over the course of a week they get to know one another.
Kirin bonds with Eidolon while out gathering firewood (Bale working on dinner). In the process he learns from Eidolon that Fenrir lives in the ring on his finger. That night, Kirin attempts to steal the ring but Bale notices. The others try to stop Kirin from stealing Fenrir but Kirin kills them both – which means that while Eidolon’s regeneration will revive him it leaves Bale dead.
Kirin brings Fenrir’s ring to Mouko to pay his part of the deal. However, Mouko shatters the ring and releases Fenrir – then orders Kirin to take him BACK to Eidolon since he wants to see if they hook up. Naturally Kirin is floored at the whimsy and insanity of this game plan.
A mere week later, Kirin attempts to return Fenrir to Eidolon, as per Mouko’s demands, and has the added complication of Marina being the one caring for the grieving knight. While he does give the ring back to Eidolon, the resulting discussion does little but reveal to Eidolon that Bale tried to kill Kirin first.
The whole ordeal is so emotionally devistating to Eidolon that he stays with Marina for the next five years.
