Through physical contact, you possess the ability to transport a target's consciousness into an alternate dimension of the world you currently inhabit. Within this realm, no being exist except for the target, and their doppelgänger—a 1:1 reflection endowed with all of their mental faculties, abilities, and experience at maximum capacity.
To escape this dimensional confinement, and break off the effects of this power, the target must eliminate their counterpart; failure to do so results in their continued entrapment. The facsimile also relentlessly seeks to kill the target, possessing boundless stamina and immunity to fatigue, unlike the trapped individual. Should the target perish, they revive after an hour, returning to the precise location where their demise occurred within the alternate dimension.
Back in the real world, you wield complete control over the target's mind. You can manifest this influence as direct control over them, like a hive mind, or having the target becoming a mindless devoted and obedient servant. The application of this power is irresistible, and you can exert control over numerous targets simultaneously if you manage to ensnare them. Moreover, you have the ability to revoke this power from any target at your discretion.
Should the target successfully overcome their counterpart and sever the mind control, you will be unable to utilize this power on them again for a duration of 24 hours. The target will have no recollection of their experience in the alternative dimension, if you so choose.
