Aglaya Lilich

Aglaya Lilich is an Inquisitor, sent from the capital to address the epidemic.

She is the sister of Nina Kaina (Lilich) and, consequently, the aunt of Maria Kain. However, according to Victor Kain, the sisters hated each other, and this hatred is not lessened even after the death of her elder sister. Therefore, Victor suggests that one reason Aglaya coming to town may be for revenge.

The Arrival Of The Inquisitor
Initially, everyone assumed that the authorities would send Inquisitors Kroy, Orff or Karminskiy, so the arrival of Lilich proved to be very unexpected. This is partly due to the fact that the Inquisitors Board had sentenced Aglaya Lilich to death.

Victor Cain makes three suggestions why Aglaya was given the mission to save the city:

1) Their information about the sentence is incorrect.

2) She was playing the role of Inquisitor illegally, having usurped her power from another.

3) The authorities provided her one last chance to rehabilitate herself, through the completion of a near-hopeless task.

The last assumption is confirmed in a conversation with Burakh by Aglaya herself.

Objective
Aglaya Lilich calls herself a servant of the law and considers the main purpose of her activities saving the city and the rule of law. According to Aglaya, a major reason that the law has been violated were miracles.

In her view, creative wonders break the thin fabric of the universe. Proceeding from this, the logical outcome is seen as her research: to save the city it is necessary to demolish the Polyhedron.

Partly this conclusion really follows from the information obtained in the process of searching for the Udurg. However, if you recall that the spirit of Scarlet Nina is currently concentrated in the Polyhedron, the brainchild of the Kains, Viktor's assumption of revenge may not seem so wrong.

But there is another nuance of conversation--that Aglaya knows who the Powers that Be are and leads the fight directly against them, and thus appears another reason for demolition of the Polyhedron.
