In an article appearing in the January 2002 edition of Star Trek: The Magazine Volume 2, Issue 9, entitled "Who is that Alien?", the following information about the Shamin Priests, which included information from Fletcher's original background notes, added:
"We are provided very little information about the Shamin Priests. The notes simply say that they were from O'Ryan's planet, which was discovered by Paddy O'Ryan in the 22nd century."
"This is the Shamin Priest from O'Ryan's planet. His undergarment is of a knit material. The tunic is a very plush material that I had woven on a hand loom. The material can't be purchased commercially. It was originally to be used in an outfit for Mr. Spock, sort of a ceremonial attire. That didn't work out so the Shamin got it. At first they wanted him dressed entirely in rags but I didn't feel that he should be all that raggedly looking wearing all this fine gold jewelry, so this is the compromise we arrived at."
Maggie Browne added:
"The Shamin's mask is another of those resin and felt creations. This one is gold plated. The mask is really gorgeous but it had a lot of bad luck. It got broken twice because someone on the set sat on it twice."
O'Ryan's Planet was a planet in the Shamin star system. The system's primary was a Class G star. Magnitude of this star was +t, which was the same brightness as Sol. O'Ryan's Planet had, by 2378, become a member of the Federation. (Star Trek: Star Charts, United Federation of Planets I & III)
