Here's a collection of journal entries I created for my DiD build not too long ago. (first time I've done this kind of thing)
During my playthrough I noted down pretty much everything that happened with the aim to put it into journal form. I've got a heap of notes of the events that have happened, but have only so far properly written up the first few days' worth of events - the rest is yet to come.
First, here's some stats and a bit of a backstory for my char (that I came up with pretty much out of nowhere):
Name: Wolfgang Reinhart
Gender: Male
Race: Nord
Born: 24th of Morning Star, 4E 170
Hometown/Birthplace: An old rural homestead, now known as Traitor's Post
Backstory: Wolfgang was born in Skyrim (see 'Hometown/Birthplace' above), before attempting to flee Skyrim with family at a young age due to the rising conflict between the Imperials and the emerging Stormcloaks (later leading to the game's Civil War).
Becoming separated from his parents whilst attempting to cross the border near Riften into Morrowind he was captured and taken to Cyrodiil.
Upon release, he spent the rest of his adolescence mostly alone, roaming the land to earn a living. Hunting and archery quickly became prominent survival skills. After many years, he began to find life in Cyrodiil had become mundane and memories of his homeland intruded more onto his mind.
After some thought, he came to the conclusion that it was time he return to Skyrim and become the grand adventurer he had dreamed of as a child, unravelling the mysteries of Skyrim's intriguing ancient past.
And now, the journal of Wolfgang Reinhart:

NB: I came up with that backstory
after I had written the journal, so there isn't really much reference to the past in the journal. (apologies for any inconsistenices

)
NBB: I started this build a couple of weeks before moving away from home for university (and didn't bring my 360 with me), so I only had limited time to progress with this character. Funnily enough, I came to an appropriate "end point" on the last day I played Skyrim before leaving, so it kinda all worked out. I might end up doing this RP journal thing some more when I can get some more Skyrimming time.
In the meantime, it'd be great to hear some feedback while I get the rest of it typed up.
