Ultima Thule

After defeating and purifying the temple of Abaddon, Conryu is enjoying a well-deserved weekend of rest and recovery. But nothing good lasts forever and a new threat soon appears.

A call from the North American Alliance president has Conryu rushing across the Pacific to investigate a battle between a Kraken and a flying Roman ship. Not exactly a situation he ever expected to find himself in.

Even worse, as he and the team try to get to the bottom of this bizarre event, an old enemy is plotting his destruction from the shadows.

Conryu will face all manner of threats as he searches for the latest demon temple.

Find out if our hero can defeat the servants of Narukami Tempest in the latest installment of The Aegis of Merlin, Ultima Thule.
