Truly sorry Amras, I'll try my best to finish, but I am overcommited at school and at home, and don't have anywhere close to as much time as I want. However, this should definitely be taking priority over some stuff I think I have time for, so I should be able to squeeze in a post every day or two.
Arwen I think it would be wonderful if you joined. It isn't terrifyingly long is it? I think it would be great if you had the time to read through the whole thing but I understand having a jammed schedule. I'm not the best at giving synopses but I will try my best.
Set in Gondolin after the Nirnaeth Arnoediad, there are three parts. Part one, Turgon sends a few score of warriors out to find some way to defeat a large army of orcs and spiders. It turns out there is a Balrog, and everyone except for Ecthelion dies (including my character up to that point). Ecthelion also kills a few innocent men (not elves), and a small army of axemen with a leader who has a black sword and a dragon helm kill the orcs and spiders while the Balrog is dealing with the elves. Ecthelion then gets a ride back to Gondolin on an eagle for part two.
Part two was mainly about the corruption of Maeglin and the fall of Gondolin. I ended up being a character I named Duilin, though not like the character in Lost Tales except in name, who was Maeglin's servant and turned out to be Turgon's personal retainer put in that position to keep an eye on Maeglin. This part was largely concerned with the actual fall of Gondolin.
Part three was after the fall. Duilin was nearly killed on the day Gondolin was attacked, but ended up unconscious and alive until a short while after the battle. He then attempts to escape Gondolin with the help of some prisoners he finds in the city while the Balrogs and a fair number of orcs have gone to the Eagles Cleft and a number of others have departed to Angband. Duilin decides instead of escaping to try to free the trapped elves, and is successfully until the Balrogs return. In the end, Thorondor flies him away and takes him to the Grave of Fingolfin, where he retrieved Ringil before returning to the survivors. They together went to join up with the survivors of Doriath, before they were swept away by the sons of Feanor. A few of them, including Tuor, Idril, Ëarendil, Elwing and Duilin escape to Círidan's havens, and Duilin realizes he has fallen in love with Idril.
I encourage you to read the whole story, there are a few plot holes, though a bit of justification makes them acceptable. Overall I feel like with a few weeks more work it could be finished rather well.
As for what character can you be, be whoever you want! If you want to be one of the characters already set out somewhat by our story or by Tolkien (though we have only been loosely following the story) then go ahead, or you can create a completely new character and have them do whatever they want. Seriously, if you want to be a 135 kilo human who drinks 6 pints of ale a day or a dainty little elf princess who turns out to be a Mair spy for Morgoth, you can (though I am not saying you would be either of them), or you can be anything in between.
