Gate Travel (Underworld)

Gate Travel is a runic spell that appears in Ultima Underworld I and II.

Description
Unlike the traditional Britannian variant, which teleports the caster to one of the eight major moongates of the realm, this runic spell transports its caster to a small moonstone associated with the enchantment. Once a magician possesses such a moonstone, they may position it in locations of significance they wish to return to with ease, and invoke this spell to return to them.

Trivia

 * In Ultima Underworld I, this spell requires but one moonstone to function (which may be found on the second level of the Abyss). In Ultima Underworld II, it requires two: one which the mage leaves in a desired location and one which they must keep on their person in order to align the spell. These twin moonstones may be retrieved from the fifth level of the Scintillus Academy and a treasure room on the third level of the Britannian sweers
