Wolf-Extra Epilogue 21 is a mod for Spear of Destiny, made by Poet. It was released on November 10, 2019.
As the title indicates, 21 levels are featured, each with their own puzzle and trickery, though not as heavy and difficult as some of Poet's earlier sets. Numerous new graphics are featured as well. Poet said this would be the final installment in the Wolf-Extra series.
