Sovereignty (conquerable space)

With Dominion, many of the sovereignty mechanics have changed. Among these is the elimination of the four-tiered Sovereignty system, and in its place now stand the three development indices. Control towers have been entirely decoupled from holding sovereignty in systems; certain POS structures rely on the effects of the new sovereignty system, but they don't actually affect sovereignty as they did prior to Dominion.
A system begins as unclaimed and neutral. At this point, any alliance may drop a TCU in the system to claim sovereignty. After five minutes, the TCU is anchored and will take 12 hours to online. The controlling corp's CEO receives a bill to pay for the TCU, whcih they must pay now, or in 12 hours the TCU will simply remain offline.
Sovereignty on its own is mostly meaningless until the system has an Infrastructure Hub; this is where the system begins to get interesting, as the controlling alliance can install upgrades based on how long they've controlled the system, or how frequently it's used for ratting or mining. The ihub takes an hour to anchor and another hour to online. Once online, the iHub renders the TCU invulnerable.
Eventually, the system offers something that a hostile alliance wants, and that they're willing to take by force. They jump in their fleet while protecting haulers who they have anchor some SBUs at two of the three gates. Three hours later, the infrastructure hub becomes vulnerable, but so is the SBU; the attackers are organized and quickly reinforce the iHub. The ihub will go into reinforced when its shield, and a second time, armor, have been depleted. There is no reinforced mode for structure.
The TCU remains invulnerable, but the iHub is now reinforced. For the next two days, it cannot be attacked, while the SBU anchored by the attackers is made invulnerable, at least until the iHub is out of reinforced. At this point, the defenders can eliminate the SBUs and secure their space once again, but if the attackers are successful, they will reinforce the iHub a second time.
Finally, the iHub falls, rendering the TCU vulnerable. The defenders still have the option of eliminating the SBUs, but if they fail, the TCU will fall, and the attackers will be able to anchor their own TCU. At this point, if they're quick enough, they can drop an iHub and reap the Military and Industrial indices that the defenders had built up, however the sovereignty index will be reset.
Claiming sovereignty begins with a TCU. The TCU takes 5 minutes to anchor and 12 hours to online. As the TCU goes online, the corp will be billed for dropping it; if this bill is not paid, the TCU will remain offline.
Sovereignty from that point is immediate; in the case of an invasion, it's possible to begin seizing control of a system in as little as a few hours.
Infrastructure Hubs and Stations
The duty of the Infrastructure hub is to provide a place for you to track index development and install upgrades. The TCU invulnerable to attacks as long as the sovereignty holder has an iHub in the system.
Stations provide the same protection to the TCU as iHubs do: TCUs are invulnerable until the attackers have anchored SBUs and claimed the station.
Reinforcement timers are different for the iHub and the Station; the iHub has two configurable 24 hour timers and the station offers two configurable 48 hour timers (these values are not absolute, as there is a two hour deviation enforced by CCP to "spice it up"). If both structures are present, but only one has been reinforced, the attacker's SBUs will remain vulnerable.
Once online, the TCU itself cannot be attacked unless it's offlined or SBUs are deployed to a majority of the stargates in that system. At this point, the TCU is vulnerable. Once the TCU is destroyed, the invading party may then drop one of their own.
There are three development indices: the Strategic index, the Military index, and the Industrial index. Each of these are divided into five tiers and increase based on different criteria. Higher levels of each index enable the controller to install different upgrades into an infrastructure hub in that system.
If there is no infrastructure hub in a given system, the indices will continue to rise and fall, however their progression details won't be available and no bonuses will be applied.

The Strategic Index the duration that an alliance has held sovereignty. Sovereignty Index levels increase based on the duration that the system has been held.
- Level 1 = Sovereignty held for 7 days.
- Level 2 = Sovereignty held for 21 days.
- Level 3 = Sovereignty held for 35 days.
- Level 4 = Sovereignty held for 65 days.
- Level 5 = Sovereignty held for 100 days.
Systems with a high ratting population will see an increase to their military index. If ratting in a given system ceases, this index will go into decline. The military index determines what kind of military upgrades can be added to the system's Infrastructure Hub.
Mining affects this index. Reduced mining in a given system will cause this index to decline. The industrial index determines what kind of industrial upgrades can be added to the system's Infrastructure Hub.
