You dismiss Lahara, grab the nearest Cherub, and order a disguise be made ready in time for the wedding!
---
The stone camp of Elephant Lake appears to be a large castle-like structure from the outside, and you quickly discover that there is no way in without blowing your disguise. The guards are keeping a tight guest list and an even tighter patrol. Luckily for you the ceremony itself takes place on an exterior balcony, so that a gathered mass of nomad dwarves may watch.
You worm your way into the first row of spectators, which consists mostly of important looking nomad dwarves. Behind you stands a multitude; hundreds of elephants, tens of thousands of soldiers, and at least as many civilians behind them. Despite its size the crowd is dead silent for the ceremony.
The groom is an ancient looking dwarf who can barely stand with a cane. You can tell at a glance that he is enthralled by your daughter. Nishi, on the other hand, wears a cold expression on her face; She is either being compelled to wed the old dwarf, or is simply using him. The ceremony itself consists of a love song preformed by a minstrel who is nearly the groom's age, a short exchange of vows, and a long kiss. You note that it is a Chestnut Dwarf, wearing the robes of your own clergy, who oversees the whole affair.
After the applause dies down, League Father Kranstill approaches the edge of the balcony to give a speech. As he talks, the age seems to melt from his voice, and the fierce determination of a much younger dwarf booms across the plains beyond the stone camp.
"My children! Feast and celebrate! Sing and dance! Drink and fornicate! Enjoy yourselves like there is no tomorrow, for there may well not be! Once this feast concludes, WE MARCH TO WAR! The mother of my bride is the great and beautiful Goddess Sunpetal, worshiped in the empire founded by that foolish peasant Walnut!"
The crowd boos and jeers at the mention of your first husband's name. "Walnut's spawn, my so called brother-in-law, the 'god-emperor' Sun-nut, currently sits the throne, but it is clear he does not deserve to do so! The scrolls of Sunpetal, and the console of my wife, are quite clear: Senshinochi, my father-in-law, was a far greater hero than Emperor Walnut! Senshinochi was loved by Sunpetal more than Emperor Walnut! And Senshinochi's blood is more worthy of ruling Sunpetal's mortal followers than the blood of Walnut!"
The old dwarf then gestures for his wife to join him at the edge of the balcony. He kisses her once more, before taking a knee, and shouting "All hail Nishi, League Mother of Elephant Lake, and True Empress of All Things Beautiful!"
The crowd erupts into cheers. Warhorns are blown. Elephants trumpet. Spears are waved.
...Crap.
A: I will let this play out. May my most worthy child win!
B: This will not fly, I should reveal myself now and crash this party!
C: This will not fly, I should confront the couple under more private circumstances!
D: I am neither a politician nor a general. I should return home, and convene a war council to get advice on how to proceed.
E: I should tip Azuma off to her sister's agenda, and depend on one twin to undo the misdeeds of the other.
