I want to see a quest that has to do with finding out HOW the dragons got back to their dominant state. I mean, like a whole guild that has its quest-line dedicated to the accounts of others from the past about how they came into being again, or where they came from. The general story arc doesn't have to be HUGE or anything, but I'd like it to go like this:
After you kill a dragon or two, you're found to regionally to be able to actually KILL dragons, and you have a Dark Elf woman approach you randomly, and she extends an invitation to you to meet up with an ex-Imperial Army foot soldier or something. Some little backwoods town, with a few houses, an inn or two, and a little guild hall that's quaint and has a nice river flowing next to it, a few dead tree stumps here and there around it.
You meet up with a man, let's call him Arvetis Imperum. He explains how he was a foot soldier back in his day after the Oblivion Crisis, and how he and the rest of the Imperial Legion tried in vain to keep civility around the empire after Martin's ascension, but ultimately there was no use as power struggles became too many, and many legion guards/patrolmen/officers were killed as a simple statement. Let's call this event the Red Diamond Feudal Years. After the legion was diluted, he attempted to leave Cyrodiil and head to Skyrim because there was a refuge for most imperial soldiers there in the southern reaches of Skyrim. Let's call this refuge town Tyarment. On his way to Tyarment, he stumbled upon Pale Pass, and found some interesting documents (that he keeps locked away in a high level chest in the basemant of the guildhall, but we don't know that yet) that seemed to suggest that Akavir were trying to infiltrate Cyrodiil (which sounds familiar, right?), when SOMETHING went wrong and the entire expedition ended up dying.
He kept luring about Pale Pass, and eventually came to a cave deep within the mountainous region, next to a frozen lake. Inside the cave were some odd bones he had never seen before, decorated with old yet still recognizable banners. Akavirian banners. He took one (and it's still up in the guildhall in his quarters) and found his way out of Pale Pass and into Skyrim. When he reached Tyarment, he explained his findings to a superior that had made his was there, but before anyone could look into it much, a raid of renegade Nords who disliked the Imperial presence of their homeland to begin with attack the town, and Arvetis just floats around for quite some years as he makes a run for it, seeing the dragons arise; and his gears begin turning.
Now, the first quests would be not so 'in-your-face' as to what the EXACT goal is for this man, but you know right off the bat that he believes the dragons came from SOMEWHERE.
Quest 1: Find a man in some town and ask him some questions about the fate of Tyarment, as Arvetis believes he knows because he was one of the reigning officers stationed there before its attack. Ask him to tell you what happened, but before he'll tell you he wants you to fetch him an item or some such that he lost years ago, a ring from his wife who died in the renegade attack. Says he lost it in a cave near the town you can find him in. Return it, and he gives you hand-written accounts from him and three others who were there during and after the battle. Bring them back to Arvetis.
Quest 2: A (let's just call Arvetis that) tells you that the accounts are somewhat contradicting, as three say one thing and one says another. He asks you to hunt down the one with the contradicting statement, as the account he wrote says he was heading for Winterhold. You go there, ask around for the man, and find he was imprisoned many years ago. You have to do a favor for the jailer, and he lets you talk to the man for a few minutes. He tells you his side of the story and says his account was a forgery, that someone that lived in Tyarment was in on the attack, but the fate of the refuge was similar. Your time with the man runs out before you can ask him who the traitor was. Report back to A.
Quest 3: A tells you that he needs to find out who the traitor was, and that the best idea is to bribe the jailer to let you actually sit down and talk to the man. You go back to the jail and offer the jailer some gold, he takes it and then kicks you out of the jail, so you must find a way to get in there. Either through magic, stealth, speech craft, or combat force, you get passed the jailer and talk to the man. He tells you that the traitor was a man from Morrowind, an Orc. He had ties to a settlement on Solstheim where some Nords apparently changed his perspective on things. The Orc obviously was rushed to safety as the battle began, and his whereabouts unknown. To know more, you need to break the man out of jail, but not yet. He asks you to bring him a quill and paper, he writes a few notes down for A, and you leave.
Quest 4: A tells you that the notes were very insightful, and that the reason the man is in jail is because he was actually found guilty of organizing the raid on Tyarment. This leads A to believe that the Orc knew he was onto him, and used some form of political leverage to get the man framed. He will get someone else to break him out of jail, because there's a more important matter for you to take care of. A mage has recently began saying he can communicate with the dragons, and there are many people who want him dead for they believe he is a dragon in disguise. You are to go to the city he is in and get him to come back to the guildhall with you. You find him, he tells you no way, and he'll only come if you first take care of the group that has formed to see his execution. You do so, and he sends you on another task, which is to ensure his lover's safety in a nearby town as he travels to the guildhall. You must escort his lover to an attack in a house out in the wilderness, and report back to A.
I dunno, I just think there's so much potential for an awesome, engrossing quest line for the origins of the dragons.
