Myth's (not connected to the SAO, more like fantasy/realword/lsci-fi/x-man mix)
the idea that pop'd in my head was like this:
a new report about humans suddenly turning into mythical creature, fully or partially, showing video of a man suddenly bursting to flames and coming out as a phoenix.
this happens worldwide and the governments (having seen to much movies) are fearing these humans might pose a tread and set out the military to exterminate the 'myth's' (as they are called)
while most myth's hide from all others, a small group (us) set out to find out what happened, what changed them and why, and what is with the weird cracks seen in the sky right before this all started
kind of a crossover between fantasy and real world/ sci-fi.
do note, what the cracks are and why this started to happen to them is already known, but can you find out XD
and while searching we still have to survive with the military tracking us and even try rescuing others and who knows what more (just the plot about why it happened and the cracks is known, all further is free to have fun XD
btw, humans that can use magic is good to ^^
so who finds it interesting and who has questions
