I won't say I know what an Imm specifically looks for, as no doubt they all have their own tastes. Just thought I would let you know how I approach them, and also thank the staff for running these events.

I approach my character roles with a concept in mind- who I want to play and what I hope to do with him. Then I turn it into more of an interesting story, something that's entertaining to write, and if it isn't I know an Imm wouldn't enjoy reading it. Have to try to entertain them since they are going to read it anyway.

Generally I use a few chapters for introduction then I wait until something happens that I anticipate will based on how the character is played to add on. Generally there is an overarching theme that I'll go through start to finish during the course of a character's life. It's not just following a path or plot, but also foreshadowing where you will go with the character, something that could be picked up on without me directly stating I choose sphere x because and cabal Y because and I'm good or evil because of z. And if you can weave a little humor into it, all the better. I'm sure that for Imms reading "mages burned my village down, I must kill all mages" for the 728535th time gets dull. So if you can come up with something unique, probably goinig to get more attention. Maybe a sphere rarely used for example, and a good relation of it to the character without the character knowing they have it.

Hope that helps, and really, I say the best roles are the ones that are fun to write and read, not the ones written just to win a role contest or get imm lovin. That's a nice perk, but should not be what it is about.
