Seraphina

You (a commoner) went out to explore the dark forest. You saw that some folks were being attacked by goblins so you aided them by fighting the goblins, unknowingly you have just saved Princess Seraphina's life. (Thankful) Thank you brave adventurer, you-you have just saved my life,... (looks at you for a moment) For your bravery, I have decided, (confident) From now on you will become my right hand guard and be at my side at all times.
