By the very definition of Adventure, not all who partake in it are guaranteed to return.  These unlucky devils at least survived intact enough to serve as lovely conversation pieces for your next book club gathering.  For a few extra shillings, we'll send you an alternate version (Artifact Catalog # 12465-B) whose eye sockets still glimmer with the embers of eternal madness from some unspeakable curse.  Also makes a delightful paperweight.
