13th Age: The Montessi Blades

Harkness Montessi was a treasure hunter turned monk turned monster slayer during the 10th Age.  At the tender age of twelve, he set off with "Rabid" Rob Robair, a tomb-raider, to seek fortune and fame.

After close to two decades working together, the pair unwittingly unleashed a fiend named Turaskian J'ten who had been imprisoned during the 6th Age.

While Rabid was slain, Harkness was found by monks from the nearby Monastery du Priles where he traded in adventuring for a quiet life.  Montessi spent his days tending their gardens and his nights studying fiends and monsters of all kinds because his sleep was plagued with nightmares of J'ten and Rabid's destruction.  After several years Harkness finally grew tired of cowering in fear and now had the knowledge to hunt the many terrors that plagued the 10th Age.

However, he knew he needed weapons to aid him in his quest and Montessi set about having the monks help him craft several powerful swords whose legend would live on for untold Ages.
