The Cryptic Warning was one of the two EE-104 Fisheyes that were stolen by the Lost Tribe of Sith for use for their armada. It was commanded by Sith Saber Querdan Dei and was used during the Jedi Queen project.
It, like most of the Fisheyes made in the Corporate Sector had no windows. This was to stop light from being picked up by enemy sensors. It also had a hull that was designed to mimic the environment around it. Another way that it was designed for stealth was its general oval shape, so it could keep a low profile. It also had a special stealth coating that would cause scans to bounce back to the ship sending them.
