An electronic interface designed to augment and enhance a marauder's siege abilities. Through a series of electromagnetic polarity field shifts, the bastion module diverts energy from the ship's propulsion and warp systems to lend additional power to its defensive capabilities.

This results in a greatly increased rate of defensive self-sustenance and a boost to the ship's overall damage resistances. It also extends the reach of all the vessel's weapon systems, allowing it to engage targets at farther ranges. Due to the ionic field created by the bastion module, most electronic warfare effects - from friend or foe both - will not affect the ship while in bastion mode. All weapons, including energy nosferatus and destabilizers, are unaffected by this field leaving the ship capacitor as one of the only vulnerable points to be found.
As a side effect of the ionic field created by the bastion module, beneficial remote repair and capacitor transfer effects are ineffective against the fitted ship while the module is active.

In addition, the lack of power to mobility subsystems means that neither standard propulsion nor warp travel are available to the ship, nor is it allowed to dock or jump until out of bastion mode.

Note: Only one bastion module can be fitted to a marauder-class ship. The increased shield boosting and armor repairing gained from the bastion module is subject to a stacking penalty when used with other modules that affect the same attribute on the ship.
