Widely considered the rudest gesture in the Itreyan Republic, it involves the raising of a fist with the fore and baby finger extended as far as the first knuckle.
After this defeat, it was presumed that Liisian resistance to Itreyan rule would falter. Itreyan occupation of its conquests was as ingenious as it was insidious - a small group of marrowborn Administratii would move into the power vacuum created by the destruction of the ruling class, and through coercion and bribery, establish a new local elite with ties to Itreya. Local sons would be sent to Godsgrave to be educated, Itreyan daughters would marry local men, wealth would flow into all the right pockets, and within a generation, the conquered would be wondering why they bothered resisting in the first place.
Not so in Liis.
After Lucius's death, a garrison of Luminatii was stationed in the Liisian capital, Elai, to oversee "assimilation". Things went well, until a cadre of elite troops still loyal to Lucius's memory raided a banquet in the former Magus King's palace. The Itreyan elite and Luminatii garrison were captured, lined up by the loyalists, and, one by one, castrated, with a red-hot blade.
The captives were then released, the elite forces barricading themselves inside the palace and awaiting inevitable retaliation. Lasting more than six months, the Siege of Elai became legend. It was said the loyalists roamed the palace battlements, holding aloft their fists with fore and baby finger extended as far as the first knuckle - a taunting gesture meant to remind the attacking Itreyans the rebels were still possessed of their "equipment", while the Itreyans' jewels had been fed to the rebel's dogs.
Though the loyalists were eventually defeated, "the knuckles" has entered common use by many of the Republic's citizens: a taunting gesture intended to flaunt superiority over an unmanned opponent.
