There is an ancient citadel located between the majority of the nations, unclaimed and unwanted in a sort of 'no-mans' land. Many expeditions have been launched towards the citadel, but all have failed by the dissappearance of the expeditions. No traces or signs of them could ever be found as the citadel remains empty. Though the land around is dead or dying from an unknown ailment. The nations stopped pursuing it in fear of causing the localized plague to spread.
Centuries have passed since the last official expeditions by this time yet the Citadel still stands. But a new issue has grown over the years. Suddenly across all the nations crops have begun to wither and die, wildlife begin to starve and die off unexpectidly. Sickness is growing and spreading and starvation of smaller settlements are causing refugees to seek the larger cities, only adding more strain to the fragile state of the nations.
The nations are beginning to grow wary of eachother, armies are mustering and cities are being fortified. Fear of global war would break out amongst the nations as food becomes scarcer and the plague worsens.
An emergancy council was called within the wastelands that border all the nations. In this council they have exhausted all other options besides one, to venture into the citadel and try to find the cause of the plague. Though no one would commit their armies to this task in fear that would open them up from an attack from their rivals. So it was decided that the best of each nation would be put forward to venture into the Citadel to find the cause and possibly reverse what ever is causing the lands to die.
