The Dark Lens is awesome! I also really liked the cool artifacts the PCs in the novels uncovered, such as the Scourge of Rkard, Belt of Kemilok, Ktandeo’s Cane… these were all really full of flavor because of their capabilities in the novels. I might go with the Scourge overall, due to the cool history and flavorful powers (such as enhanced hearing).
