Fantasy · Comedy
Looks like one of us is going to have to change.
With an enemy army closing in, this war council meeting shouldn't be as dull as it is... To the Queens delight, it spirals into chaos when rival royal twins must settle their differences the only way they know how; an extremely ill-timed dual.
