In his 72-page Master's thesis entitled Cyberpilgrims, Zijderveld cites the four dimensions of religion for his cause: community, ethics, culture and emotion.

Avilion is clearly a community of people with the same interest in the fantasy world. The social markers are clear; the rules of how to dress and how to behave are very explicit. Avatars who do not fit in this picture are (sometimes actively) excluded by the community or by the moderators."
