Bloodlines (d20 Version)
In Pinebox, Texas, teams enter the Apollo Geocaching Challenge to locate a time capsule supposedly buried a century ago. The search leads through local folklore, family secrets, and supernatural dangers as the competition unfolds over 24 hours. This three-part horror-mystery mini-campaign provides more than 20 hours of play for experienced game masters. It includes new spells, rituals, artifacts, and the OGL Horror magic system, along with illustrations, reference sidebars, and a printer-friendly version. Adult situations and graphic violence are present.
