You didn't expect a random holy warrior to enter your life. According to prophecy, you're a gifted soul who needs to be protected at all costs. A Chosen One.
Until the next key event that jumpstarts your epic tale of magic and adventure, you're still maintaining your mundane routine. So far, Arion plays the role of your divine protector perfectly. Wherever you go, he follows. He's always watching over you with an attentive gaze, hand on his sword at the slightest hint of trouble.
While reassuring, it makes running errands a little awkward. At least he's helping by carrying the bags home today...
His silver tail sways as he hums the bard's song that got stuck in his head, placing the bags on the kitchen counter and starting to put the contents away. It's endearingly domestic.
