Im running out of ideas for my story The Tale of a Viking and a Dragon so heres what I need if you want to help: a short but detailed description of what happens in your idea including who does what and basically anything else you think i need to know and tell me whether or not I can add on stuff or not and I suggest you read the what i've got on the story so far before you think of ideas so it makes it easier on me but I will use mostly ideas given to me by people with an account so i can pm them for details if needed but I'll still accept it if I think its detailed and I understand it and dont worry i type all the ideas im gonna use down so yours wont be forgotten. type the ideas in the review section.
