The Shadows enter Hyperspace in a manner that allows them to become invisible. The exact method used doesn't matter. This would be represented by a cloaking device in SE4. Not a ship hull with cloaking built in, but an actual comp that could be placed on any ship. I though the Shadows would have this already. This is why I suggested the Vorlons get a small ship size (smaller than Scout) which has a cloaking ability built-in, instead of an actual cloaking component. Although, they can enter special pockets (dimensions?) in Hyperspace, which allows them to hide from the younger races. So maybe they could get 1 type of cloaking, which they and the Shadows have scanners that can see. The Shadows would get another type of cloaking, which only they could see. Then, add Stealth devices, which races such as the Minbari have, which would be for the younger races to use. The ancient races would be able to easily detect these (scanner at level 1 ancient tech).
