Oooh. I forgot it is a type of magic plotdevice telescope I had never heard of before and you might of well made up on the spot. Sorry.

The cheif engineer walks up to Tangent. "So, cheif, this is how the Pylon works, as of your request. The universe has a natural tendancy to resist dimensional travel. It tries to reject things moving through dimesions and send them back to their source. However, all spells and technologies that have the power to move between dimensions also have the power to overcome this. What the Pylon does isn't preventing the travel, it aids the expelling force to the point nothing can overcome it."

This means anything can travel between the dimesions to the protected dimesion. It would just be instantly expelled to it's point of origin. So that means even L_G's magic plotdevice spell would work, since all it does is force through shields, not abolish the natural forces of the universe.
