Beginning the Short Story

The first thing I realized with my short story is that I was not sure where to start. After a bit of thought, I started with a kind of dream that Fenrir was having. I plan on using flashbacks to recount his story to the audience, but it seems a very daunting task to do it all in around 1000 words. The second obstacle was the irony. I plan on making Fenrir seem like a misunderstood "monster" (if he could be called that). My version of Fenrir would be an honourable wolf who was not a coward, and was deceived by scheming gods. But I'm not sure how to do that and put it into my story. So far, I think the irony incorporation is proving to be the hardest obstacle to overcome. What I find exciting is that I can essentially write the aftermath of one of the most famous myths in Norse mythology. I can describe my own interpretations and descriptions of the characters and their personalities, as well as write an account of the processing behind Fenrir's decision, which kind of gives rise to the details that are missing in the actual Norse myth. My draft is coming along a bit slowly, since I'm trying to incorporate irony, but not doing a very good job of it. It's coming along nicely, but I think if I knew more on how to incorporate the irony, it would be moving faster.
