Hyperspace disturbance beyond the edge of the galaxy

It was originally thought that hyperspace travel outside the galaxy was impossible because of a hyperspace disturbance at the end the galaxy. The goal of the Outbound Flight Project was to use the combined abilities of six Jedi Masters and twelve Jedi Knights to penetrate the disturbance using the Force. The Yuuzhan Vong found that they were able to bypass it at an area they called Vector Prime. The Yuuzhan Vong possibly entered the edge of the Crispin system, that was at the very edge of the Galaxy and set up the Crispin asteroid field that gased at the Intergalactic Void.

Mandalorians Discovery
Years before the events of Outbound Flight the Mandalorians came across a strange unknown ship/creature, this beast or ship was incredibly fast and in one shot destroyed a Mandalorian battle ship during the Mandalorian Wars. The remaining ships chased after the ship/creature and followed it hyperspace route, after hours of flight the ships intercepting the unkown beast suddenly dropped out of Hyperspace. Electrial currents ran through the ship disabling communications and their Hyperdrive, after realising the electrical current held them back from their pursuit they turned back towards the main fleet. None of this data was recorded.
