Tome of the Undergates (The Aeons' Gate, Book 1)

Adventurer. The term has long been synonymous with cutthroat, murderer, savage, zealot, and heathen. And Lenk, an errant young man with only a sword and a decidedly unpleasant voice in his head, counts all five among his best and only associates. Loathed by society and spurned by all merciful gods, he and his band are recruited for only the vilest of jobs.
