Flash out wherever the Just

Context:

Failed to get the meaning of "the Just" here.

Does it mean fairness/righteousness?


Thanks in anticipation

“Defenseless under the night
Our world in stupor lies;
Yet, dotted everywhere,
Ironic points of light
Flash out wherever the Just
Exchange their messages:
May I, composed like them
Of Eros and of dust,
Beleaguered by the same
Negation and despair,
Show an affirming flame.”
