(Oh...this. Can't have you start godmoding, after all.)
The Master and it's servants paid the image on the wall no heed. At least, it seemed like that. In truth, the Master had sensed the magic in the aura and thus prepared a special surprise for the intruder. As soon as the image spoke, a trigger was activated and all the magic that was absorbed in the last 2 days suddenly overloaded and exploded. Although the Master fully expected the invader to survive such a backlash, at least such a move would set it back to the same power level as it was during their previous bout. All the otter did was tip his hand, right into a stronger hand.
The Umbreon, similarly, ignored the otter. Instead, after casting the fortification spell on the ritual and overseeing the last of the preparations, returned over to the Glaceon and spoke: "As soon as the ritual is complete and you become one of us, a Shadow Pokemon, you will sire in a new breed of Mons, those that were not infused with such power after the fact, but were born with it. Born to serve the Master...hahahaha!" The Ice-type realized what this meant and could only scream in terror, a scream that ultimately fell deaf, as the only ones to hear it were those who were going to turn her into their slave...
(Alright, and let's avoid blatant godmoding, alright, K_H?)
