"One's honor is tantamount to one's very existence."
This decree by the very first Firelord, Tengoku Ryuji, is the founding principle to which he established the unification of the seven clans of flame into the Fire Nation.
It is also this very principle that the right to "strike and leave" had been established. It gave strict but brutal guidelines to resolve offenses made by those of a lower class to those who outrank them.
The offended party had 1 day to enact their retaliation, to which the offending party had the right to defend themselves. Should the offending party refuse or flee, they and their family would be subject to harsh punishment… Health workers and the like were exempt to the right for obvious reasons. And the right doesn't extend to nonbenders unless they had a member within their family who could firebend and fight on their behalf.
The surviving party of the skirmish still had to report the encounter and their recollection of the events leading to it, as well as spend a mandatory reflection period in their home regardless of whether he was deemed to be righteous or not. And being deemed to not be just also had steep penalties.
With the merged hierarchy of the seven clans into one body, the continued infighting due to past factional disputes made these guidelines necessary. But as time went on, the right had been exploited by the clan heads to eliminate rising threats amongst each other.
This was one of many subjects of reformation made by Firelord Zoryu to centralize power away from the clans. No longer did the right belong to the higher class of the two, as two people of equal standing could now invoke it via a formal challenge. The right now had to be exercised via a public duel with at least one ranking or formerly ranked official present, to which the challenge shall take place at a later date. And the duel would end only when one participant has been burned.
Should the challenged party refuse, their honor was tainted, but the maximum punishment they could receive was banishment via decree from the Firelord.
To reflect the amendments to the right, it would then on be referred to as "Agni Kai"
The right continued to exist lawfully until it was abolished by Firelord Zuko after the 100 year war. But even though it was no longer a legal right, the fire duel still persists to this day…
The arena filled with voices of confusion as two opponents were present within the field.
They had already been given the signal to commence what was the first of two semi-final matches, but they knelt with their backs facing each other. After a count of ten, they finally stood and faced each other.
One of them was a boy with a light complexion, hair as black as gecko-ravens, and eyes as gold as the sun. The other was a boy of slightly more tan complexion, with dark brown hair the color of platypus-bears, and heterochromatic eyes; his right eye being gold and his left is as blue as the ocean.
"I'm sorry it has to be this way, Cousin!"
"No you're not."
And with that time for pre-fight quips was done. They knew what was on the line, and this was the perfect venue to resolve it.
