While watching Konosuba I came across following sentence:

「我が真紅の流出もて 白き世界を **覆さん** 」

What troubles me is the 「覆さん」. The translation used an imperative here, what
fits most of the other spells in the series as well; however I don't know how
this ending can be an imperative. I've read this post ([Meaning of ぬ added to
連用形 / masu-stem, as in
風立ちぬ](https://japanese.stackexchange.com/questions/12585/meaning-of-%E3%81%AC-
added-to-%E9%80%A3%E7%94%A8%E5%BD%A2-masu-stem-as-
in-%E9%A2%A8%E7%AB%8B%E3%81%A1%E3%81%AC/12587#12587)) already and assumed that
in above stated sentence the general idea is the same. Nevertheless before I
start making wrong suggestions I would like to know what grammar works behind
「覆さん」as an imperative (if that is even possible).
