Tenosia is a distant land, not far from Agatha. It has a hot desert climate, with lots of sand and palm trees. In 1266, after uniting the continent of Agatha, King Alfonso Argon attempted to conquer Tenosia in a failed crusade that he would not live to see the end of. The Tenosian soldiers were acclimated to the harsh weather and environment, and their light chain armor allowed them to maneuver more easily and cut down the ill-prepared Agathians, whose heavy armor bogged them down while many burned to a crisp in the hot sunlight, with ease. The capital of Tenosia is the city of Jaburdan. Its buildings are made mainly of rotting wooden planks and crumbling sandstone bricks, though there is an effective irrigation system that provides the citizens with water, with many aqueducts and a flowing river running through the city. Most of Jaburdan lies in ruin thanks to Agatha's failed conquests.
Little else is known about Tenosia, but General Malric Terrowin of the Mason Order used the fear of a Tenosian counter-invasion (after the failed Crusade and death of King Argon) to gather support from the Agathian population. This led to him taking over Agatha. Indirectly, the ensuing war between the Order and the Argon Loyalists has its roots grounded in the hot desert sands of Tenosia.
It is assumed that the weapon Infidel's Bane is a war trophy from a fallen Tenosian warrior.
