You decide to attend the performance.
Alogn with (some of) your courtiers, your maidservants, and little Rinilda, you visit the local ampitheatre that was built by the state's money.
The highlights of this performance are actually moments where the chorus shines; instead of just two solid choruses, there are parts when one voice from the chorus speaks to the actor, and the choral voice is then echo'd by the rest of its chorus, and then they sing praise or insults at the hero ('the First King'), together in melodic intonation; the other chorus has deeper voices and mostly advises or tempts the hero to do evil or otherwise think of himself. Quite dynamic, this, and even further developed from what the writer told you earlier.
The story explains the Descent of Pantheon, the enlightenment of Man due to that event, and the creation of the First Kingdom under the First King (The Hero), who then had to solve several difficult crises - but all problems were fixed when he did what Pantheon ('The Good Chorus') suggested, even if that meant hardship and pain, while all the easy yet cruel alternatives offered by King's advisors and warlords ('The Evil Chorus') were discarded. The First Queen ('The Lady') was always there, shooing away the Evil Chorus or offering warmth and support to the Hero when he began to doubt himself.
The ending scene is as follows.
First King (raising a sword): "This my Kingdom! The first Kingdom of Man! The greatest in all history!"
Wife (embracing him): "Proud is my heart and mind!" (to Good Chorus) "Praise be! He is the greatest of Kings!"
Good Chorus (praising): "Praise be! He embodies the virtues of Pantheon!"
Evil Chorus (tempting): "Now seize the power of Gods, to become King of Heavens!"
Good Chorus (begging): "Be virtuous! Resist the temptation! Praise be!"
Evil Chorus (hissing): "You can reach greater heights! Why stop here, when you can have so much more? All you need to do, is pierce them!!"
Wife (shielding First King from Evil Chorus with her own body): "Be silent, do not tempt him! No more!!"
First King (steps before the Wife): "No more doubt, there is in me! For I am glad with what I have, for it is clad in blessing of Pantheon!" (to the Evil Chorus) "To the underworld with you, fiends!"
The First King 'stabs' the members of Evil Chorus, who all collapse.
First King (triumphiantly): "And now, the land is free of temptation, strife, and evil, and Pantheon reigns supreme!"
Good Chorus (praising): "Praise be the one who is with the Pantheon, for he will be bright and just! May he reign forever~!" Trumpets, drums and horns then issued a cacophonic yet triumphant noise, as the Good Chorus collapsed around the First King, who raised the sword up, prideful and victorious.
The spectators all burst into applause, shouting and cheering.
A) Is this the thing I wasted so much money on!?
B) BRAVO! BRAVO! ENCORE!!
