My wife, back when we were in high school, had a home-crafted 'religion' of moon-worship and magic. (This after growing up Mormon, right?) Her philosophies were so persusasive that she 'converted' a Catholic from Mexico and a Shinto-ist from Japan (both exchange students) as well as a few of the locals in Sequim, Washington, USA -- THE town with with the HIGHEST ratio of chuches to people in the western half of the United States. Quite an accomplishment.
So, she named herself Majik.
I started going out with her (fell under her spell?), and decided I should choose a nick that went alongside hers without elbowing in on her meme-space too much, so I decided on Essence.
I've been Essence everywhere I've gone online ever since.
