Joseph L. Cooperstein spends most of his time lamenting the fact that there is currently only one human habitat in low Earth orbit, and none at all in the rest of space. When he's not doing that, he is either sketching dragons on napkins or running scenarios in his Skull-Mounted Reality Simulator & Thinking Device™. In the brief moments between those strenuous and time-consuming activities, he—as you might imagine—writes. He has a degree in Theater and studied literature extensively during his college years.
He is known, where he is known online, as Leisandir, although sometimes he spells it with an 'e' for no particularly good reason.
