NIGHTFANG SWALE
CAMPAIGN
YOU WILL NOT FIND MANY PLACES VILER THAN THE
DISGUSTING BOG WE MUST CROSS TO GET TO LORD BLACKBURN'S CASTLE.
GATHERED WITCHES FILL THE AIR WITH THEIR
UNSEEMLY CHANTING, WHICH MESHES PERFECTLY WITH
THE CRIES OF WILD, HUNGRY ANIMALS. THESE ARE THE
BEINGS THAT SERVE A ONCE GREAT, NOBLE KNIGHT.
FROM THE PUTRID WATERS, DOZENS OF DEAD BODIES
STARE AT US WITH EMPTY EYES...
