Words of Power
Certain Words of Power have long been used in various Ultima games to represent the spells they conjure. Each is also linked to an english letter and a Runic Symbol, though in Ultima Online they are primarily used for spellcasting and are rarely seen elsewhere.
The symbols used to represent Ultima's runes are taken from the ancient Norse alphabet, which also gave them separate magical meanings (though this author is uncertain as to how closely the two versions match).
Examples Of Use
Vas Kal An Mani In Corp Hur Tym
Great Summon Negate Life Cause Death Wind Time
Also, on the back of the The Second Age handbook this phrase is written in runic symbols:
The Incan monkey god peered through the leaves of the great book and saw the dawning of a new age - An age whose like has seldom been beheld by man.
Bet & Bal
The term "Bet", though frequently appearing in other Ultima games, is not actually used in Ultima Online. It is seemingly replaced by "Bal", which is used by some Necromancy spells. This new word is not defined and no runic symbol is known to go with it, but it could be interpreted as "Evil" or "Demon".
