Wraiths
Wraiths

The alien vessels which have become known as wraiths to the Alliance navy are a complete mystery. The do not appear to belong to any known alien race and do not favour one side or the other in the war (Wraith vessels have been observed to both ignore vessels from both sides and attack both with equal fury), instead carrying on slowly travailing through space until they encounter a planet or installation, in which case they have been known to scan these for a short while before leaving again whilst in other cases ignoring the planet or installation altogether as they pass through a system.
The vessels themselves are larger then any vessel yet encountered by either side in the war and posses technology and weapons that are extremely advanced and powerful, even out gunning Alliance heavy dreadnoughts. Whilst they usually travel slowly through space and do not appear to show an interest in anything around them unless they pause to scan a planet or installation, if has been noted on numerous occasions that if a vessel approaches too closely to them the Wraith will suddenly transform from a slow moving, defenceless vessel to a extremely manoeuvrable, fast, powerful warship. It is unclear why this happens but is assumed to be as a result of the Wraith possible considering the short distance between vessels as a threat. In addition no successful contact has ever been achieved with a Wraith vessel, no access doors have even been discovered on the hull (bringing into question how the crew enter/leave their vessels) and Wraith ships have only ever been observed/encountered on their own, never in groups.
