Ozone

Ozone refers to the area that Orstland used to occupy before the Era of War.

The Ozone was once divided into many tribes bickering for land, rights and wealth. The first king of Orstland Heagart united the tribes under a single banner. The Artigan Empire invaded from the west. At the same time the south rebelled and became the Southern Republic.

The Ozone is filled with varying concentrations of a gas called trioxide. Trioxide is what gives the Ozone its unique character. The gas has a similar oxidising power to fluorine. This means that it reacts violently with most metals. Plants and animals protect themselves from the air with special fluids, skin, bark, sap or structure which reacts to form an impermeable layer. The high oxygen level means that food will spoil in minutes unless treated with the chemicals from nature. The ozone is on a slope, highest on the west and lowest on the east. Trioxide concentration is the opposite.

The eastern border of the Ozone is one long cliff called the continental shelf into trioxide chasm where the gas comes from. The trioxide in trioxide chasm is too strong causing anything thrown in to spontaneously combust. The famous explorer Cunnock is rumoured to have discovered a route into the chasm.

The north of the Ozone is the frozen lands. Humans brought up in warm swamps and fields never bothered to discover if live existed there.

The western border is a mountain range. Where trioxide is too heavy to go, neither does the ozone extend. Most explorers to venture west do not return. Cunnock is the notable exception.
