When the Final Hyren quest lands the kids in Bograth, they discover the strange, swamp-laden realm...even stranger than before. The rampant void energy poisoning the swamp has changed the Bograthians - and their Guardian Hyren - into mutated, rat-like creatures who transform when darkness falls. Edyn gets infected, so Tony and Strag race to turn her - and the realm - back to normal.—Anonymous
