There's a quite common misconception that orcs are a group of barbaric monsters, people who love to fight, kill, and destroy. And while true that the orcish cults of the Destroyer that love to murder, pillage, and raze villages, not every orc took on those aspects. Orcs were created in his image, but while he was a god of endless passion. Each orc set out to find what thing they are truly passionate about.
For some orcs, that passion is fighting, those tend to go off and become soldiers, gladiators, or adventurers. But many tend to have much more mundane passions in life, many find love in horticulture, acting, painting, smithing, animal husbandry, and much more. An orc's lifelong passion could be anything in life, and many take it as their primary mission in youth to find out what theirs is.
