The Matriarch was enjoying the fruits of her political success.
She incited the opposition to act against the invaders and got them killed by Prince Shak's and others' teams.
Then, she punished the invaders by banishing them into the eternal hell "Mad Zone".
The whole event was shining the contrast between the two sides.
The matriarch who's successful in disposing of the invaders and the opposition who were pathetically slaughtered.
This created an unprecedented appeal for the Matriarch that she was placed alongside the legendary leaders of their race.
As she deliberately spread more and more 'rumors' about herself, the half-truths and half-lies were exaggerated by the crowd and turned her into a living legend.
Even a common courtesan could now see that the Matriarch was no longer a ruler but something akin to hope for their race and kingdom.
