Earth... this term used to mean Mankind... until technology finally gave humanity the ability to explore space. As humans began to seek out adventure and new territories beyond the safe boundaries of Earth, the number of colonists who were not born on the home planet increased.

In the 22nd century almost 1 billion people were living on various planets throughout the Solar system.

With the growth of their economic and military power, new tensions arose between Earth and the colonies. Their leaders agreed that a peaceful solution was needed and Earth's Moon was chosen to host a meeting between them...

In Heagemonia Legions of Irons, the player has to explore and conquer the galaxy as the head of his fleet, planning colonization, terraforming planets, managing his resources and deciding on the appropriate technological research to lead mankind where he wants it to go.

Research, combined with a top-notch spy network, will enable the player to survive in a stellar system which is much more dangerous than it would first appear to be. Black holes, asteroid fields, nebulas, cosmic clouds and wormholes as well as alien races... make each fleet sortie a perilous affair.
