On The Cover A dragonlord rides upon a mighty bronze dragon. Disclaimer: The authors accept no responsibility for what happens to you in the lands of Thylea. This includes (but is not limited to): discovering your nymph lover has unexpected tastes in captivity, bronze dragons who insist they are gods (and get very offended if you disagree), and surprise raids by drooling, axe wielding berserkers from a place called Grimnir. Should you encounter the latter, we strongly recommend surrendering all valuables immediately. Resistance may result in Blood Eagle. If you do not know what that is, remain blissfully ignorant. Intended for ages 18+
