EMPIRE! CWBG VIII: It's Not An Event Without A Few Corpses

[ImperatorV]

Also, Osmium is a metal and thus conducts heat, which is important: This statue would no doubt be sitting in the sun, which would heat its exterior over time. At three miles up, wind speeds tend to rise, which means that cloud erosion will almost certainly occur over time. Dislodged Osmium particles react with O2 to form Osmium Tetroxide, a ludicrously deadly poisonous substance that sublimates at about room temperature and would now be placed in a perfect position for said wind to scatter it across the land, causing thousands of cases of potentially lethal pulmonary edema and blindness.

Assuming that it's real-world Osmium, anyway. Chemistry tends to fall apart somewhat in fantasy land.

It's probably a different metal that happens to be named Osmium and share some traits with the real world metal. At least, that will be my head-cannon unless he can come up with some very good reasons everyone hasn't died yet. And why there is so much of it.
