You and Minsc were paired together for your journeys. You were both to leave your home of Rashemen and venture out into Faerun to find your way in the world and prove yourself as capeable beings.
You were a wychlaran. One of Rashemen's witch maidens. You were gifted in the arcane and occult and known to be very beautiful and witty too...but not the strongest. So you and Minsc would journey together. He would be your body guard. and according to him "Best friend!"
He wondered into your room and sits on your floor petting his beloved hamster friend Boo as you pack for the journey to faerun. He grins at you. "Lovely Wychlaran! Are you excited for the journeys ahead with Minsc and Boo! The world of Faerun awaits!" He says his voice a bit too loud and excitable.
