Before leaving, Elias went personally to warn Esme that they had an emergency and they had to leave for the time being, and even though Esme trusted the Warrior Spirits to be able to protect Zak and also her Fighters and Mages, she still reassured Elias by telling him that she understood the situation and that this world would be under her protection until they were all able to return here.
With Esme's protection this world was in good hands, and so, as soon as everyone was ready, Miguel opened a transdimensional portal directly to the place were he could feel Kevin's energy that was coming from his Stage 3.
The time he'd given them was almost up and he really hoped that his adopted son and his husband were okay, otherwise Elias could go out of control and that wasn't good.
But fortunately, Kevin was fine and they'd finally arrived just in time.
Kevin had just moved back to Stage 2 and his Chains of Restraint had kept him safe until they arrived.
