Here is information about the last three:

Time Gate
Construction: After waiting out the final age, order your peasents/slaves to build a Time Gate. After constructing the Time Gate, you are left with an empty ring.
Countdown Activation: Clicking on the Time Gate will show a technology to you called Time Travel. It costs a fifth of the resources needed to construct the Time Gate. It will take a while to research, but once it is done the countdown will activate.
Loss of the Time Gate: Unfortunately, you will only have one chance to build the Time Gate, and if it is destroyed, you will lose that option.

Election
Area of Control: Like in the civilisation games, instead of just a normal minimap, you will be given an option to switch to the 'normal' modes (economy, military, full) or the 'boundaries' mode. The boundaries mode will show which player is controlling which area, according to the colors of the player. Only three buildings give area of control: City Centers, Town Centers, Fortresses.
Election: This will happen twenty minutes into the game if you have enabled it. The player with the most area of control wins. In the unlikely event of the areas being the same, a special occurance happens. In the last few Age games you will win or lose. But this will happen if the two areas are the same:

Before carrying on to the time conquest condition, I will elaborate the 'assigning mages' thing.

Unlike in previous age games, you will have to assign mages to buildings for any techs to be researched there. Mages are very poor fighters, but you can allow them to cast spells such as Blizzard or Thunderbolt. If you assign a mage, you will get a notification and research will be available, albout slow. Assigning more mages speeds up research. Mages are slow but cheap, and with their huge LOS are effective scouts.

Time Conquest
Research: Available in the final age, it is a very expensive tech, and goes extremely slowly. You may need to assign every mage you have, which is easily done using the 'supreme summon' button, and every mage will assign to the given task.
Victory: The research will finish and you will be rewarded with victory.

AGES
Dark Age (1)
Magic Age (2)
Heroic Age (3)
Chronologic Age, or Chrono Age (4)

TOWN CENTERS
Settlements may be built anywhere on the map, but are weak and only support a little population. You can upgrade each, individualy, to a Town Center, and you can assign mages to upgrade each to a City Center, at a cost. These increase in HP and pop support until the City Center which is 9000HP and supports 20 pop.

Thanks to Jonathan1222 for this one:

SAVE POINTS
In the main menu, at any time, you may select Save Point. If the Time Gate victory is not enabled but you build one, you will go straight back to that Save Point.

More information coming soon.
