Minions of an ancient and immortal vampire seek to release him and usher in an era of darkness. Engage in a race against time in an adventure that ranges from the arctic to the very sun itself. Suitable for Pathfinder for characters 9th to 12th.
“Do you know why you fear the dark? Do you know why the accursed star of day gives you comfort? Your ancestors knew why. The night once ruled the day, yes! What splendid nights those were! My master was Lord of the Night, who ruled over you mortal fools like your farmers rule over your cattle! The world was right, then, everything in its proper place. We hunted, and we fed, and we killed, and we paid tribute to our master, whose darkness outshone the sun! Most importantly, we kept you in line, my sheep.” - Duncan Redback, servant of the vampire king.
