This module offers stable 24/7 performance and allows a DM to have complete-dynamic control over the many additional features programmed into the PVW by traveling to the special areas and interacting with placeable objects. Seviss Isles (R4b) offers extensive additional features and 480 detailed areas; includes an expansive surface from the frigid northern mountains into the southern sand-swept deserts; deep below through dungeons that link into the Underdark and across the planes to Baator, Cania. Covering these extensive areas are 5 detailed bird-eye view maps along with a �Player�s Guide� (36 pages) and �Dungeon Master�s Guide� (68 pages). Seviss Isles provides a PVW which players and DMs may campaign within 'as is'; or expand into a customized RPG setting for their particular role-playing style, by either modifying the Seviss Isles module or linking-in adventure modules through area transitions.
