Inversion with ‘here’ and ‘there’
Inversion can happen after here, and after there when it is as an adverb of place. We can use a main verb without an auxiliary verb or modal verb:

Little is used in a negative sense in inversions. Little did they know, for example, means “they didn’t know”:
Little did they know that he had stolen all of their money. (They didn’t know he had stolen all of their money)
Little did he know that they would never meet again. (He didn’t know that they would never meet again.)
Little did he understand the situation.
