Hard-science Tolkien fan-writing

Stefan sez: “I recently put my game designer hat back on and am revising a long-out-of-print roleplaying sourcebook for David Brin’s SF universe. This means doing lots of “research,” trying to suck timelines and hard science facts out of prose written to entertain. A web-search showed that someone beat me to it: Alberto Monteiro, a former net-acquaintance. But even more remarkable than his Jijo timeline is the way he determined the orbits of the three moons!) is his hard-science analysis of Middle Earth history.” Link Discuss
