I think you've seen some of my Dragon musings. That would probably be an appropriate vessel for collaboration.
It's a free-standing plot, because it happens in an area of the Galaxy or Universe unconnected to Earth, although a connection could be implied.
My main reason for wanting to write this one is to interject scientific plausibility into the legends of dragons. My dragons fly according to scientific principles.
There's also a couple of completely unscientific plot elements that I like. I harbor no niggling regard for consistency.
Random thoughts here and there, like a side enterprise between some ‘irresponsible dragons’ and ‘human miscreants’ involving the creation of alcoholic beverages referred to by the locals as “Fizzy Lizard”.
