A galactic war. A war between alien species. Like is seen in the Doctor Who series.

Orginates from the latin words alius (meaning other, English use - alien) and bellum (meaning war, English use - belligerence).
There was a massive alibellum between the martians and the sontarians.
There is an alibellum in the air, war will break out in the next few years.
