Charging to the Depths
Reign and the others quickly glanced back at the portal before sending Greenie through it to tell people that this portal will not be working till further notice. After all, the fog would soon engulf the portal, and they didn't want to see anybody making a mistake and walking through it, thus coming in contact with a Tier IV monster and dying.
There was also the chance that the fog could somehow corrupt the portal, or that the monsters would be able to walk through it immediately and wreak havoc in Doncaster, thus they disabled it, but they didn't move it as they didn't have time to do so.
M'azgara's elites were with them before, but now, only 3 of them were left to help them out while everybody else went back to Doncaster and the other territories. Even though most of the barriers had been lifted for quite some time now, it was still rare for powerful monsters to go to the weaker areas, but after the notification, it was as if a switch had been flipped.
