Klingons

Thanks to Qibitum, I've been spending a little time with Erik “Techgnosis” Davis' website, where I found an article about Klingon religious practices.

in a darkened Ramada Inn conference room, the Klingons prepare for their ritual, Tera'daq Tlhinganghom'mey. The hulking beings, all members or allies of the Karizan Empire, file past a table in silence, depositing their energy weapons in a pile. Incense chokes the room as twelve aliens, both male and female, take their seats around an altar. Candlelight reflects off the latex ridges of some foreheads, and the soundtrack of Bram Stoker's Dracula plays on a nearby tape deck. The impressively-built Mok walks counter-clockwise about the altar, brandishing a hammer of Thor as he invokes the heroes of old and demands their presence at the gathering. The candles shake as he slams the hammer on the table. “We are between the worlds,” he announces.
....
There are more differences between fandom and Neopaganism than similarities, and even the Karizans insisted that the Tera'daq ritual was a “show-piece”—not a real Pagan ritual but a way to play with their magical leanings within the Trek mythos. But by performing their spiritual sensibilities in the trappings of a TV show, the Karizans also revived the oldest derivation of the word “fan:” fanaticus, a devotee of the ancient mystery cults.

In asking what drives Klingons, Davis ends up digging into the relationship between religious belief and religious practice, fiction and tradition, performed self and essential self, and all that jazz.
