<Snipped quote by Terminal>Well, you may need to watch more Star Trek and popular sci-fi in general.
Weird space creatures with abstract biology (if ou can even call it as such) and capabilities that match or even surpass starships are relatively common.

As for the area, I thought about it being their territory for hunting.
Otherwise because we talk about creatures that can move (and perhaps may even capable of FTL) you can't really put down their location.[/quote]

I was really bummed when they killed off the Crystalline Entity.

Fascinating as that was to the Federation though, and as dangerous as it was, the fact of the matter is that it was a footnote to a massive interstellar nation. You can include any number of such creatures as ambient background details (True Vacuum Shenanigans ho), localized events and dynamic incidents (it might keep popping in to say hello whenever you meet with Nation X or it might be harassing your border outposts) and within your own nation's territory, but they are not going to get actual map-space dedicated to them. Sorry.

In essence, 'Map Anomalies' is a category reserved exclusively for big wacky energy vortexes and similar anomalies of that nature. Think the Nexus for example (although I think we can agree that was definitely not canon).

EDIT:

Yep, that calculation is correct. Good to see people are interpreting the map correctly.
