Xorinite wisp

Xorinite Wisps are a race of sentient balls of light, each a part of a collective mind. The wisps identify themselves as Xorinia, a transdimensional information broker. Though the Wisps do not appear to have individual personalities, they do have a central government, the Undrian Council, and refer to themselves as a 'community'. The Wisps are very old - they gave Zog the Armageddon spell over 700.000 years ago, although they don't see the spell as something powerful.

In Ultima IV and V, Wisps regularly attacked the Avatar and did not discuss business. Negotiations were first opened in Ultima VI.

The Avatar first met the Wisps in Ultima VI in the Deep Forest west of Yew. The Wisps gave him/her the Armageddon spell as a gift, but wanted the Book of Mantras for more services. Bringing it from the Lycaeum, the Avatar had the choice between information or a really huge amount of gold (as much as the party can actually carry).

The Wisps were also met in the Abyss in Ultima Underworld and the valley of Eodon in Savage Empire. In Eodon, the Wisps gave the Avatar a freebie, describing what exactly had happened to make Eodon the way it was. They were so fascinated by this situation that they didn't want anything in return. In the Abyss, the Wisps conducted a little test on the Avatar, by tempting him/her with a really powerful spell (Armageddon!). The Avatar resisted and the Wisp explained to the Avatar that he/she learned an important lesson: not all information is beneficial.

In Ultima VII, wisps could be seen in Spiritwood and the Deep Forest. The Wisps first paid no attention to the Avatar and the Companions; after Magaretha said that the Wisps had important information to share about the Time Lord, the Avatar made inquiries with Taylor at Empath Abbey. The party then sought the aid of the Emps, who provided a special whistle to make a contact with the Wisps. In exchange for setting up a meeting with the Time Lord, Xorinia wanted Alagner's notebook. The Avatar got more than he/she bargained for; while the Wisps threw in information on the Guardian and the Black Gate, they also sold out Alagner to the Guardian; the sage was immediately murdered by the Fellowship.

The last encounter with the Wisps was in Ultima Underworld II. The Avatar met them in the blue zone of the Ethereal Void. Demanding to know what happened to Bishop, they gave him/her in return information about what happened to the Trilkhai and their history (although other information can be asked for as well).

The Wisps weren't seen again after this. In Ultima VIII, there are reports of mysterious balls of light in the Plateau. Though while this does strongly point to the Wisps, it's uncertain if this really refers to them.

Trivia

 * From Ultima VI onward, the Wisps are invincible, and the player shouldn't dare to attack them, as it would be his/her end.
 * The Wisp appearing in the first Underworld game is quite different physically from all other games. This one consists of several small balls of light and explains that Wisps can send small parts of themselves away to gather information.
