Fallen ranks

My family the bloodletters were one of the greatest back then we were ranked the best assassins family 1,000 years ago. Now we are the lowest of all the families. This family has gotten cruel over the time that we have lost ranks we only have gotten to take tiny jobs for a decent pay. But I was born into this family not being any help to them so they banished me when I was 5 and since I've been gone they've climbed up 5 ranks. I'm proud of what my family has done I wish could be a help to them. that's why I wanna get stronger because "once I get stronger I can come back and prove my worth" that's what my father said as he banished me, but dont get my family wrong they still care for me they sent me to a assassin school so I can become stronger and they give me money every month for rent. It's not a bad family they have just fallen to a low point.
