Gatecraft [860]
---------------
Long ago the Ancients, a race of wise men who ruled the land with
the aid of powerful magic, constructed a network of teleportation
gateways to connect distant cities.  As the reach of their magical
portals grew, so grew the reach of their armies and knowledge.  At
their height the rule of the Ancients extended to every corner of
the known world, and beyond.

With the passing of the Ancients, the system of gates fell into
disuse and decay, and now retains only a hint of its former majesty.
Gatecraft, once practiced by the most common among the Ancients, has
since been forgotten by nearly all men.

The school of Gatecraft retains the only knowledge of the use of
these mystical portals.  Because knowledge of Gates can be a powerful
tool or weapon, Gatecraft spells are jealously guarded even within
the school.  Some aspects of Gatecraft, such as the secret of their
construction, have been completely lost.

The following skills may be studied directly once Gatecraft is known:
