"Queia" means "fell" (past tense of "fall").
Here, 'queia' is used as the past imperfect form of the verb 'caure' (to fall), describing an ongoing or habitual action in the past.

The rain was falling on the cobblestone streets.
In this sentence, 'queia' again serves as the past imperfect of 'caure', used to describe an action in progress at a specific past moment.

Here, 'queia' is the same verb form, referring to the metaphorical falling of the night in this narrative.
