The Zephon demo offered a few of the possible warlords to play. They are very much like civilization factions: while the basic city buildings are the same for everyone, the warlord will determine starting units, the mixture of offensive technologies, bring in a few of their own research subjects, and offer some wide-ranging changes. For example, the Fallen Soldier gives early access to the Human tech tree, grants all the biological units regeneration and balances that out with increased upkeep. Meanwhile, the Emulated Mind starts with Cyber tech, is restricted to a single city, and has a big stonking cannon on the roof for harassing neutrals that come close.
