It concerns the exploits of two earthlings, tavern owner Travis Wilder and ER doctor Grace Beckett, as well as those of their allies, both throughout their home world of Earth and the otherworld of Eldh.
Grace, combating the same plague using magic and medicine, stumbles upon an ancient conspiracy that could spell doom for both worlds.
Travis and Grace return to Denver to seek medical aid for the Eldhish knight Beltan, gravely wounded in a battle with a Necromancer.
Grace returns to Eldh to find the legendary sword Fellring, the key to defeating her enemy, the dreaded Pale King.
Having at last vanquished the Pale King, Grace attempted to usher Eldh into a new age of peace, while Travis lives quietly in modern-day London.
