Although I do not know much about it yet, I really enjoy learning about the history of Middle Earth, and I like recreating possible scenarios in the LCG. I'm trying to figure out where our heroes were during the 17 year span that this game is supposed to cover.
Hobbits:
Bilbo - In 3001, he traveled with 3 dwarves (unnamed in LotR, but named Nar, Anar, and Hannar in History of Middle Earth) from the Shire to Dale and the Lonely Mountain, and settled in Rivendell in 3002.
Frodo - in the Shire the whole time.
Rohan:
Eowyn - In 3001, she was about 6 years old! By 3018, she was 23, but was caring for her uncle Theoden, whose health was very poor. It is unlikely she was galavanting about on adventures in the interim, but it is remotely possible, I suppose.
Theodred - 23 years old in 3001 (same age as Boromir). I'm sure he goes on quests during the next 17 years, but I don't know much about him until he dies the day before Boromir dies.
Dunhere - don't know much about him, except that he died in 3019 defending Minas Tirith.
Dunedain:
Aragorn - Searched for Gollum beginning in 3001. Finally finds Gollum and catches him in February, 3018. Then delivers him to Legolas' father in Mirkwood in March. (Gollum escapes in June.)
Gondor:
Boromir - Boromir is 23 years old in 3001. In 3018, he is involved in holding Osgiliath.
Prince Imrahil - Was 46 years old in 3001, but was not "Prince" until 3010, at age 55. By 3017, he was 62 years old and a grandpa! Yet he fought valiantly in the war of the ring and survived it.
Denethor - Steward of Gondor during the entire 17-year span. Probably stayed in Minas Tirith most of the time, but then, defending in his strong point in the game, anyway.
Elves:
Legolas - in August of 3018, Legolas is sent to Rivendell to let them know that Gollum escaped and that the Mirkwood elves had lost his trail.
Glorfindell - Don't know anything about him before he rides to Frodo's rescue.
Dwarves:
Gloin - 218 years old in 3001.
Gimli - 122 years old in 3001 (11 years older than Bilbo).
Dain Ironfoot - King under the mountain during the whole period. Friend/Ally of Brand.
Dwalin -
Dale:
Brand - Became King of Dale in 3007 (years after Bilbo's visit in 3001-3002). Friend/ally of Dain Ironfoot.
If you know any more details about these heroes during that time span, please post here and maybe I'll edit this post to fill in those details.
