The (More Than) Complete Cast of CVRPG
Heroes, Villains, Low-lives, and Agents of Leisure
Golems are created, almost exclusively, to act as servants for a wizard or priest (or a client of a wizard or priest). Golems are reliable workers, never tiring, never needing to eat or drink. Most importantly, they never need to be paid, as they have almost no need for money (beyond the occasional bit of clay to repair themselves, and often clay can just be found).
That was the life of the Golem, eventual hero, but one-time servant. Created by a wizard, paid for by dwarves, the Golem was made specifically to guard a dwarven cave that lead into the dwarven city (that, itself, lead into a dwarven mine). Golems, being the perfect 24-hour security system, worked better for guarding dwarven mines than just about anything else dwarves had ever tried (much better than any mortal guards, and slightly more effective than the dwarves' old strategy of putting out signs saying "certainly no dwarven mines in this cave").
And so for many years (centuries, really), the Golem guarded his cave. He'd patrol, close up unneeded tunnels, ward off the attacks of the occasional band of adventurers, and, always, go back to guarding the entrance of the cave.
Occasionally he cleaned, too, but that was only when he was really bored. Still, even then, he never did windows.
And then, one day, the dwarves were all gone, most lost in a great civil war. There was no one left to guard. The cave was still there, however, and so for a time the Golem continued to guard it.
One day, many years later, three heroes (our favorite heroes) ventured into the dwarf cave. There they met with the Golem, and after much discussing, the Golem realized he was free of his duty... and so he left to explore the world and seek out a new life for himself.
The life of a hero.
The Golem works as a hero, but that's mostly because he doesn't have anything better to do with his skill set of: hitting things, hitting other things, and creatively hitting two things at once. The matters of humans really don't concern him. He's outlived humans, dwarves, elves, and even a few vampires. Mortals have a short span, and Golems have a long one.
That said, he will still help anyone that asks him for his aid. As a golem, the Golem naturally feels the need to "serve". If someone asks him to do something, invariably he will do it just because it's what he knows to do.
