Listen to this man <| sep |> I haven ' t tried it on W 10 , but I can try next week if you like . I haven ' t had any problems with battery life . I read somewhere that someone made it 400 hours with all the lights off . Longest I ' ve gone is a 40 hour work week with lights off and turning it off at the end of each day . <| sep |> I will try my hand as well . I am writing about Dacus who as a six year old child was sold as a slave by his selfish brother . To gain favor with the demons who tortured and killed his parents in front of him when they raided his village . Since that day Dacus got a burning hatred that grew as he was abused and tortured by his masters day after day , while working at the mines . Until after 4 years an cataclysmic event has caused most of slaves from the mine to turn into unthinkable abominations , he was the only one who came out barely alive , carving a bloody path through the mines with a pickaxe . For that the demons saw that the boy could be useful for them as they put their elite slaves to teach him the basics of fighting before throwing him into the battlefield where he fought for years , getting a great reputation for his brutality . Being sure of his talent the demon chief decided to make him his bodyguard , but not before making a mark on his body which would allow the chief to manipulate his body in order to ensure that he won ' t rebel against them , as he still tried to find an opening to kill his owner , containing his wrath . But in order to ensure his loyalty , his owner forced him to commit some of the most horrible acts of known to mankind , trying to break him . In that moment he snapped unleashing all his hatred , as he had gone berserk , breaking the power of his mark and killing the demon he served for all these years . But with a price as the fury combined with the magic of the broken mark , burned his entire body . Now freed after a life of servitude , Dacus will try to find his own purpose in life . But the hatred for his former masters still remained . I am aware that I may have made a lot of mistakes as it ' s the first time I am writing a backstory for a character . So , if you can , tell me where I did wrong .
