Loosely based on the webcomic "Homestuck", I present to you: THE INTERACTIVE TUG STORY!
Here's how this works: I will post a section of the story, and then you (plural you - as in, the readers) will PM me what you think the characters should do. I will choose one (or more) of the submitted commands and base the next section of the story off them. Commands can be submitted for ANY character that I've introduced, but not all commands will be used in any given section. Also, you can refer to things I haven't introduced in your commands - eg. telling a character to find something that I haven't said exists yet. If I use a command that mentions something like this, I will add it to the story. (You can put miscellaneous comments in this thread.) I'll update the story several times per day, assuming I have commands to work with.
So, the first section of the story:
Pandora is your average 16-year-old girl, except in one respect. Said respect is that she has just woken up in the middle of a forest, with no memory of how she got there. She gets up, confused. Or tries to, at any rate... She realizes that her arms are tied together at the wrists and elbows behind her back, making getting up hard. Now she starts to panic. But not too much. She isn't in any immediate danger, and this is probably just a lucid dream.
It takes a while, but she is able to get up, after which she begins walking off in a random direction. As she walks, she realizes that she's wearing a long purple dress, not her nightgown. That's interesting.
EDIT: Oh, you can also email me commands instead of PMing them, if I'm out of PM space or if you don't have an account. fanofblindfolds@gmail.com
