Or, yeah, that theory of Derleth dampening its powers. Because a space stone here, it'd have the same limitations as anyone with teleporting abilities. Maybe that power option being weakened or inaccessible makes the stone easier to handle. But also, ouch, that is way too much power for one person to have. And seek out... Like I know people wield the stones all the time, but bonding with it is a whole other matter...
