In this world, magic is infused within the land. To tap into that magical energy, the people wove magic into metal and created magical tools. One such accomplishment was the Etherite Transit System

Centuries ago in the world, sorcerers created large siege weapons called Mage Hammers. They were large battering rams that converted magic, ether, into kinetic force. Many models were tried, but the best one was created during a siege.

The castle was magically fortified, resisting the strongest of blows or the fiercest of spells. But a general noticed something - while their forces were unable to enter, the enemy forces were unable to leave. So she constructed a rail system to allow the large metal battering ram to build up speed and power. The result was broken castle walls and a new system of transportation.

Instead of letting the built up kinetic force dissipate in a powerful blow, it allows the vehicle to propel itself under the most efficient circumstances.

Lesser tracks have been tried, but the most efficient one follows along a certain magic-dense tract of land.

The rail system was created in the equivalent of our medieval era. They had fast efficient cross-continental travel.
