A few crafty users of teleportation magic have devised a neat little trick.
Thankfully for the rest of us, they decided to share their secret to their
pupils, which gradually found its way into the studies of most novice users of
magic. By preparing a special incantation, one can set a safe location, and,
in the time of great peril, be instantly  whisked there from danger. While
this art is very unrefined yet, it is responsible for saving many novices from
 situations they have blundered into unexpectedly. There are also a few more
powerful beings who have used this spell to save their hide, but due to pride,
this isn't as commonly known case by case... Note: It is also rumored that
extreme  knowledge of the teleportation magics can ease the stress  of the
sudden teleportation on the user.
