I humbly beg help locating a fan faction which i somehow misplaced on my computer! I do not know the title or the author. I can describe the plot as much as I can remember, however. After Sam left for Stanford, and John, of course, abandoned Dean, waving all the red flags of a lifetime of unforgivable neglect and emotional abuse against his firstborn. Dean decides to continue hunting under the tutelage of his some-time stepfather, and full-time research assistant Bobby Singer.
When Dean winds up tracking through the countryside, in pursuit of some creature or other, he quickly deduces that he has shifted into another dimension, with no clue as how to return home. After retracing his steps, and no visible yellow brick road signs, Dean is left with the survival training his father beat into him at a young age. Reduced to distant recons and nightly raids for clothing and food scraps, Dean realized everybody here possesses rather large wing-like appendages. Furthermore, Dean's brief recons have uncovered a very dark picture of a "culture" comprised of a two-caste system. The winged people are the "upper class" warriors, while those without those appendages are at the lowest of lower class (a.k.a. slaves), doing all manual labor in the fields, and serving in houses, and maintenance in towns. These lower castes appear to have had their wings brutally hacked-off by warrior sadists during some sort of ceremony to empress upon them their new lot in life.
Nauseating recon totally over, Dean hauls ass away from these mutilating sickos. While trying to quietly steal some provisions from a isolated manor far, far, away from that disturbing village, Dean is overpowered by a black-winged and totally hot homeowner called Castiel. After the "What the F*** are you? questions and manhandling inspections, the reality of the shit storm hits. Castiel seems to be a rather intrigued, enlightened, and chill angel, who would never tattle on Dean's alien differences.
Since Castiel is something of a eccentric hermit to his own kind, he decides to hide Dean in his upstairs apartment, providing him with food, clothing, and a bed until everything can be sorted out. With no one else to interact with, Dean and Castiel become closer, sharing stories of their lives and adventures from their different realities. Dean expresses his horrific shock when he learns that the "slaves" are in fact warriors who were bested three times in combat and mutilated to prove they are worthless to Michael's armies. After many talkings-to Castiel about the needless cruelty and sadism of such practices, Castiel agrees with Dean that these practices are atrocities.
After much planning Dean convinces Castiel to travel back to his reality, where life is far from perfect, but still better than this bullsh*t! Even so, neither man knows the direct route back to the field Dean crossed over through, so they enlist Castiel's brother Gabriel to gather intel on areas strange animals are spotted roaming. When they have the nearest coordinates, Michael decides he wants to challenge Castiel to blood combat to prove who's the better warrior. Dean, of course, is of the school of "screw this noise" but Castiel cannot back down without loosing face. Castiel looses to Michael two times and almost lost a wing on the third before Dean's message sunk through his thick angel head. He hauls ass after Dean to his reality and leaves all that pointless deadly pea cocking reality behind. Time to start a new life where being a warrior means actually battling evil and protecting those who cannot defend themselves. Castiel can find true self-respect with a smoking hot righteous man!
