Read Namespace.

Wikis are allowed up to 3 additional namespaces (and their corresponding Talks). I'll echo Tupka's admonition that simply dividing the mainspace content is poor usage for this. What you described is better served by Categories.

Some of the examples some wikis have used them for include RPG or Roleplay for wikis which do them, Fan fiction, dividing Hero/Heroic from Villain/Villainy, etc.

Consider your requests carefully. You only have a limited number of (paired) additional namespaces. Plan wisely.
