There is no duration on Zceryll's summons ability, so you get to keep your summoned aliens indefinitely unless they are dispelled. There's also no limit on the number of summons you can have at once, so you can just summon more, and more, and more, and more, until you've amassed an infinite army. This is probably not the intent.
