So this is a specific area of suggestions of only Story line ideas. I understand there is a Beyond topic but thats general suggestions. This is specific Suggestions of storys as write a outline of a story here.
For Example you want to suggest a story/questline for the Arena (if its added for the next game)
My one would be along the lines of this: (just a specific quest idea)
"Welcome to the Conjurers tree. (i liked the perks idea). You're but a novice and have little understanding as to how to summon" in echoing sound whispered the Bosmer. Quest learn more about conjuration, ask in the Oaken Library. *notes* I found a bosmer called juanes he asked me to meet in the guarded round the back of the Library. (you meet him round the back of the library in the guarded. in the centre is a stone circle and by the looks of it Juanes has drawn a rune marking with "a flower yet to be named". He asks me what i would like to summon. (options may vary from what you have seen in the world so far, and what 'juanes' knows about the creature) Options: Atronach, Daedra, Undead, creature. (player selects one). juanes: hmmn, and what kind. (just say for example you chose creature then Flying imp. Juanes proceeds to place a skull of an imp down on one of the runes and the flower is on another, one gold piece on the third, on the fourth is some meat and on the fifth juanes, he then asks "do you really wish to learn about conjuration" options: Yes, No (leave) (special mission linked to this says) Yes(lie). (player selects yes) Juanes starts uttering noises then clamps hands together, purple starts to appear on his hands then he slams his hands down in the centre of the circle with runes in it. There is a Flash of light and a flying imp appears. Juanes gets up and touches the imp and with another flash of light the flying imp is gone, juanes then approaches you and says "do you wish to learn these spells" (player selects yes) Juanes says that was a Rune summon: Flying imp, so long as you have the right items on you may place a rune down and if an enemy comes close to it the creature will spawn. (player learns Rune summon: Flying Imp).
