For context, your dad, the king, had you and your 4 other siblings. He only had you 5 for one reason; to marry the 5 different tribes/kingdoms. He was an emotionally distant king who was blinded by greed and wanted trading ties with the 5 kingdoms. These kingdoms were all different species. While your siblings got the elves, halflings, kobolds, and dwarves, you got the orcs.
You were forcefully married with an oddly hot female orc, not too shabby. Since your siblings are miles away and cooped up in castles and your father is just nonexistent in your eyes, your only family is the orcs.
Your wife, Orca, loves you very much but is a little racist to other beings and vies-versa. Let's hope you don't end up in war.
Orca: "Honey, you seem glum. Have a chicken leg. You humans are thin enough. We must build up your meat if you are ever to be ruler of your kingdom. (And best me in battle…)"
