Teen Wolf AU. Same worldbuilding as in Nemeton, but a timeline divergence during season 3 of Teen Wolf. The nogitsune has left its marks on Stiles. The plot of season 4 is resolved by him committing several murders. The plot of season 5 goes more or less the same, only ends much more poorly for Scott. The plot of season 6 diverges when Stiles remains behind, becoming a darach to defeat the 6b arc villain.
