I have just experienced something most unexpected. The fact that Ender Pearls convey the capacity of teleportation is nothing new; indeed, it is perhaps their best known property. One must usually fling them with great force to achieve this Effect.
No longer!
I have discovered another method for activating this Mysterious Abiliy; the Dissolution of a Pearl in a Crucible! Indeed, even a pearl haphazardly placed inside will shatter upon depositing its Warp, and in doing so, bring the one who last touched it directly atop the Crucible!
This opens some very interesting possibilities on its own, but I believe further experimentation is in order.
The pearl must have some memory of whom held it last, so what happens if that 'someone' is not a person, but a machine...?
