URRU

:''Not to be confused with Uru.''
The 'UrRu' or 'Mystics' are gentle and wise inhabitants of the planet Thra in the film ''The Dark Crystal''.
The characters are the opposites of the Skeksis. Although they had inherited the mystical wisdom of the urSkeks, they were powerless to use it outside their own valley, since the division had robbed them of their ability to take action.
In the film, the UrRu are represented by puppets engineered under the direction of Jim Henson. Conceptual designer Brian Froud described them as "partly old wizard, partly some sort of strange animal." They have gentle features and runic patterns on their faces. They all lean on walking sticks and have four arms each, they have a thick, black blood.
At the film's beginning, there are ten Mystics, each representating an aspect of the Hebrew Sefiroth, only eight lived to be reunited with their Skesis counterparts:

★ the Master urSu, i.e. Keter

★ the Ritual Master urZah i.e. Chochmah

★ the Healer urIm i.e. Binah

★ the Chanter urSol i.e. Chesed

★ the Alchemist urTih i.e. Guevurah

★ the Cook urAmaj i.e. Tiferet

★ the Herbalist urNol i.e. Netzah

★ the Scribe urAk i.e. Hod

★ the Numerologist urYod i.e. Yesod
