Denied. Your character's personality is friendly, but there is no direct evidence in your back story showing how he is a friendly person without inferring that he is. There are probably more personality traits that can be found in your back story but not listed. You should take this time to try to add more to the list. Also, you should take the time to improving some of the grammar in your back story. Some of the sentences are improper and don't make any sense. You should also go into detail about how the other members of the group got 'caught' and by whom, although that might have just been the sentence not making sense. Also explain what skill's you were taught, or if it was you teaching skills to others; Just explain what the skills were about. I also recommend that you describe in detail one event your character went through that impacted his life greatly. Was your character well respected in the group or at the bottom of the chain? Overall, fix the back story and let me know when it is fixed. Have a great day!
