Each attempt to bring down the void would end in failure, as the crew shifted tactics. Rather than use portals, they used beaming instead to beam a canister of sleeping gas into the place where most of the life signs had been detected on the ship. This happened after they put anti teleportation and anti-portal enchantments on it so it could not be removed that way, and also made it impervious to being transmuted.
The EAMS were something that would need to be dealt with and so the EAMS would be practically swallowed by portals launched at them, sending them to the sun in the Sol System which would cause them to be burnt to a crisp and destroyed that way. This would happen to every EAM the Anrufe sent out so the EAM tactic would be useless.
Now to disrupt the barriers, a construct of a sword slammed into the barriers several times using MWCA technology that had recently been incorporated. Missiles and Muramasa Beams were fired through portals at the barriers and the station. In addition, a spell crafted to work like the EAMS was used against the barriers so that it could eat all the energy of the barriers, and the energy of the ones casting the barriers until they were nothing but an empty husk. The silence field, and void warp continued to exist since the EAMs were all gone now.
