The Colossus

These warriors are the embodiment of raw power. They wield giant weapons with the same skill that other fighters do smaller weapons. Rumored to be the descendants of titans, the mythic first creations of the gods in some realms, or the greatest of the true giant races in others, one thing is clear, these warriors wield great power. Despite their origin, very few have ever been seen. The tales of these warriors defeating entire armies alone, slaying ancient dragons solo, and many other feats are often written of as myth or bardic embellishment. those who gain these powers by other means are often the result of forbidden rituals, gruesome or violent experimentation or the mortal child of a godlike creature, and often live the life of a wondering adventurer. They are often drawn to the most challenging of work to test the limits of their strength.
