This Q6 normal manna Myth Parallel is an annomolly is several ways. First, the geography and geophysics of
Big Planet(named for the Jack Vance
novel) are radically different from Homeline's Earth. The continents are shaped nothing like those of Homeline Earth and added to that the planet is far larger than Homeline Earth. Measurements made by Homeline scientists show the planet to have a circumpherence of around 125,000 statute miles, and thus an area twenty-five times as great as Homeline Earth. But the gravity is only 0.97G. However, the peoples of this world all resemble Homeline cultures and societies of the 200BCE-200CE period. The laguages, cultures, literature, religions, and many more traits seem identical, even with the presence of Magic and functional Wizards! The atmospheric pressure is 18psi at sea level, 20% more than Homeland Earth. Although human groups seem nearly unchanged when compared to Homeline Earth, the flora and fanna of this parallel includes large numbers of creatures that look like survivors form previous geological eras including most of the
Pleistocene megafunna and some dinosaurs and
Pterosaurs. Fully mythological creatures like dragons, unicorns, and griffins, haven't been seen, but are widely reported. Homeline can't tell if these creatures are present or their stories are simply much more popular than on Homeline Earth.
Amoung the strange chages that seem to have few if any cultural effects are the flying ships (I'm cribbing from
Space 1889 here, look at the Martian War Kites and Mercant Kites) which are the main arteries of commerce and comunication. The keels of these ships are alchemical wonders.
Basically, sword and sorcery with real human cultures. Prehistoric beasts replace myhic beasts, but their roles are much the same. Homeline, Centrum, and the Cabal, are fairly neutral to each other on this parallel. There are interesting exotic trade goods here. This exotic world can distact agents from the threats that both of their other competitors present. Scemes to replace Homeline agents with doubles are most workable in this environment. Still, swagmen, particularly human trafickers, love this vast chaotic world. As almost all human groups on this world practise slavery it's very easy to legally buy slaves. Some of these slaves will find the conditions of servatude under the swagmen, brutal as it is, far better than anything else they've ever faced, and may not wish to be freed.
