Star Trek The Idic Epidemic

I.D.I.C -- Infinite Diversity in Infinite Combination. More than just a simple credo, for those of the planet Vulcan it is the cornerstone of their philosophy.

A plague whose origins are somehow rooted in the concept of I.D.I.C. itself. A plague that threatens to tear down that centuries-old maxim and replace it with an even older concept.
