Creature Themes page is done. I just went ahead and simplified it. Felt like I'd be rewriting some stuff if I tried to codify the themes themselves so I just took the time out to explain how theme was extremely changeable in a multigenre setting like BrikWars. The Bestiary grows slowly closer to being done. There are a few entries I'm just not sure what to do with, like the Bayounikals and Munchfigs.
I also went ahead and undid the edit to the Factions Template. My reasoning is thus. First, it messed with a bunch of existing faction articles. Second, we don't want templates to be intrusive. They're there to summarize, quickly and in a single location (sidebar), the faction at a glance. They're also there to provide a vaguely unifying theme to the faction pages as a whole, so that readers can quickly and easily identify the article as a Faction article. So they need to be conspicuous but they shouldn't intrude overmuch on the writer's creativity. Players should feel free to structure and headline their articles as they please. Some commonality across articles is definitely appreciated as it makes the wiki look nicer on the whole but rigidly defining content wouldn't be a good way to go about that. The generic format of the sidebar and category templates work just fine in that regard. Wikiers are perfectly capable of defining their own stuff.
