Old picture because I meant to post one month ago but out of laziness I didn't. Also sorry for the quality 
My first and current Skyrim character (aka my baby girl) Aghella ! 

Current level as I am typing : 53 
Age : mid or late 20's 
Sexuality : bi with a preference for Argonians and Orcs 
Major stats : light armor, sneak, one-handed, speech, archery and lockpicking (blocking and two-handed are getting closer tho) 
Side : Neutral. She gives 0 shit about politics all she wants is living a good life with her friends, husband and children. She helps whoever pays well or (as she does have a good heart deep down) feels pity of, and if you annoy her and did wrong to others, *snaps neck stealthly*, and hates betraying those who helped her or did nothing to her (so screw most Daedra quests and the Blades). Also she prays the Nines and she loathes vampires and it truely took her time before trusting Serana. She values her followers she makes solid bonds with and is annoyed at her huscarls she sees as unsincere as they work for her only because a jarl told them to. She HATES dark magic (vampires and most daedras are in that field to her) and thus, despite the fact she sees herself as a manipulating assassin-thief-warrior, she had no regret in destroying the Dark Brotherhood. They already traumatized her long, loooong ago when she joined them thinking they were normal assassins... 

So for her story, know that I discovered the TES lore only 3 months ago and got Skyrim soon after that. I am very new to it so correct me (still not spoilering as I plan playing other games PLEASE) if her story makes no sense to the continuity The way I see it, she is my character in Skyrim, TESO (I started TESO first ; didn't touch it in 3 months seeing how inferior it was in comparison), Morrowind (started playing but mods don't work, the DLCs deleted themselves, the fighting hability is awful and let's not talk about the health bar, I gave up) and Oblivion (plan to buy it soon). How, you may ask !? All those are different times. Weeeeeell... 
Aghella was born 16 years before TES 111 in Morrowind. Orphaned egg, she was raised with other orphaned beasts extremely bad, physically abused and having to steal food and money to survive. She was not given an Argonian name but as an eagle tried to steal her as an egg, and that eagle in Latin is "aquila", she was named with something sounding similar. She got stealing and money loving habits, but one day she was caught and had to kill for the first time to defend herself ; that got her to jail just before the game starts. Back then, as she was alone all her life, she was a full little shit, not hesitating to steal that one elf's life savings in the first village. But as the game progresses, she makes friends, learns how to fight and kill better, starts to look onto the consequences of her action, learns how to be more cheerful (To her friends' chagrin, she is the pun and "clumsy when nervous" and "joking when did something wrong to lighten up the mood" type) and decides she could also sometimes help people the way she wanted to be helped, hence the secondary quests. Still she doesn't find killing and stealing amoral and keeps doing so if necessary or when there is a good reason (a bandit won't be missed). She keeps wandering around homeless though even though loved by more people A few years later, now as a young adult, she got to jail again after being caught stealing (old habits die hard) and TES 1V starts. This time when wandering in new lands she gets more status and finally gets her own homes and even falls in love and (thanks to mods) marries a handsome Argonian. She hears of the Dark Brotherhood and is interested... But horror ! They worship a dead woman and are summoned by a dark magic ritual ! She gets scared and runs away swearing she will kill them the next time she will see them. Also the Oblivion crisis making her doubt no more about Daedras : most of them are evil assholes she wishes to stab. Everything is almost perfect after that, almost because upon finding out she is sterile and can't have a child with her husband, their marriage goes downhill, they get more and more distant, and despite all the affection she has for him she can't help cheating Then one night she got kidnapped and sacrificed, waking up in an undead world at the start of TESO (being a game not from the main series I allow myself to put it where I want in my HC timeline lol). Horrified, where was she, where was her husband, how could she save herself ?! Fortunately a group of people rescued her and brought back to life. But... to their lifetime. As that undead world whose name I forgot is out of time, any person from any era meets there... and they were from the First Era. OH FUCK. OH FUUUUCK. She gotta gotta find a way to go home and find her husband ! But... the people who found her unconscious and brought her to their village did help her... She still had to help them, just hoping it wouldn't change history. She spends some time wandering around from land to land there making new friends and forgetting her husband more and more in the arms of some bedfriends, but she still wants to be home in her time, and reassure those who knew her she resurrected (even him, he didn't deserve to be worried). One day after all the quests are over (I SUPPOSE IT'S POSSIBLE !?)... she hears about how the Elder Scrolls are beyond time and space. Time, hm ?... She could maybe finally go home ! Ready to find Elder Scrolls again this time to trime travel to the future, she goes where they were indicated to be in her normal time. She finds one, thanks and hugs farewell her companions, and uses it. She wakes up in a freaking battlefield, confused as ever, running around in confused awoken panic for her life. Especially as both sides, Imperials and some blue clad warriors, attacked her one thinking she was with the other and vice versa. She ultimately gets knocked out by an Imperial, and later wakes up in a wagon with strangers talking about some sort of conflict !? And she is gonna be beheaded ?! AND A FREAKING DRAGON DESPITE HOW THEY GOT EXTINCT !?! She quickly ran away with an Imperial who pitied her and followed him, and asked a moment where they were. Skyrim... She then read somewhere around Riverwood a book saying when they were... 4th Era. OH NO. She went too far in the future !... and now she is in the middle of Civil War!... won't this Nightmare stop ?! But then she realized. If dragons are now extinct. But are back. Does it have to do with time travelling ?! Probably ! She gotta go find that black dragon and Elder Scrolls again ! But meanwhile she helps people again, learnt a strange word from a strange wall, killed a dragon and swallowed its soul, is able to shout and is called "dragonborn", finds out that the dragon wants to destroy the world so she also has to stop him, gets new statuses and homes, finally becomes the mom she always wishes to be by adoptiong orphans, gets pet dogs she loves with Meeko following her everywhere, falls in love again and marries again, destroys the Dark Brotherhood once and for all... so when she finds an Elder Scroll at last... she just can't go back. Especially as she would let her new friends and family alone with Alduin. So after she killed him at last, she decides to stay. She is happy in Skyrim
