It is two days after Kyoshi's death. The world has come scant breaths away from declarations of war three times in the last two days. Twice world leaders have come to the air nomads asking for sanctuary, saying that they feared for their lives. The summit grinds on, a fixed point of reference that people can use to structure their days amid the maelstrom. A third delegate from each nation has been added, and the newest member of the Air Nomad delegation spends the gaps between the speeches to arrange and rearrange lines of figures in his neat thick handwriting. The Air Nation has gone from having a small budget shortfall to having an impossible logistical nightmare, and the bulk of that nightmare falls on the back of the new delegate.
His name is Abbot Rinzen. He is almost sixty. He feels every year.
The western air nation is not merely out of communication. It is under attack. He reads lines of numbers on a sheet and wordlessly calculates how many lives may already have been lost.
He goes to the heads of the other countries. The air nomads have always been a beggar nation, subsisting on donations instead of taxation and nationalization, and he will beg with a stiff back and a chart of the estimated casualties. The air nomads do not typically engage in trade, but he will barter every resource they aren't using to muster the evacuation or care for the displaced in the aftermath. Once again Abbot Rinzen is pressed to mortgage the future, he has already redirected all of his plans for economic improvement that aren't directly related to the evacuation's needs but some of the funds are already spent so yes, two years from now they will pay more if that's what it takes to get letters of credit today, he is checking his estimates three times to ensure he doesn't bankrupt his nation but this trade through time is worth it. He has to face the head of the east temple and ask her to stop all charitable expenses in these four resources, that the air nomads cannot pay or provide food for anyone else until this harrowing moment is passed. She says yes, of course. He feels worse somehow than if she had fought back instead of yielding immediately.
People keep offering to fight for the western temple. Somehow that's worse. All these hot blooded young men and women with swords rattling in their sheaths. Rinzen tells them over and over again, we are pacifists, this is not a defensive war, this is an evacuation. We do not need your warships, we do not need your weapons, we need this many transports at these locations and these many resources to create extra transports and to feed and shelter the people we evacuate. Please do not kill on our behalf. Please do help us get everyone out.
Abbot Rinzen has drawn up a plan to effect the evacuation of the west in two days. People congratulate it, cheer for the rescue. One old general nods in quiet understanding of what that plan achieves. That night as he pens the final motions and requests, Abbot Rinzen allows himself five minutes to sit and cry alone by candlelight. If he'd started earlier, realized what the silence meant faster, or just been thriftier with spare resources in the halcyon years before, he would get there a whole day sooner.
There's an old airbender sage whose koan repeats in Rinzen's mind. "Let go of your earthly tether. Enter the void. Empty and become the wind." Abbot Rinzen has known for years in a quiet place in the back of his mind, known but not emphasized, that he is a poor airbender. These people are an earthly tether, and he is attached. And yet he has never felt lighter, never moved with this sense of absolute sense of becoming the wind. No other philosophy could achieve this, no fire could burn hot enough to fight this army from such a poor start, no earthen wall could hold them out for long enough, even water could not run as fast as they will need. Only air can pass through this narrow gap and save these people.
The next day hundreds of sky bison take flight. The day after that, they will fly headfirst into the storm of war. By the third day it will all be over one way or another, everyone either fled or left behind to the iron calculus of logistics. The right thing in the right place, and right now the right place for the air nation is anywhere but the west. And now there is no special purpose for the old abbot. With the letters already in flight he's gone from the only member of his nation who could do this to being just another tired old man in a city suddenly devolving into civil war.
Young fools are trying to brawl in the streets, and he asks them to stop and talk things out. Somehow it works. Two dozen people armed with steel and the elements and somehow they stop to listen to him long enough to agree to keep talking tomorrow. Someone mentions how much they trust him, how capable he is as a mediator because he can obviously enforce the talks go peacefully. They think he's such a powerful bender. Abbot Rinzen expected to die when he stepped in between the groups and held his palms up to both sides as steady as the earth. That night, he doesn't know what to do to stop those same hands from shaking. Tomorrow comes. Then another day, and another. Each one a generous donation, more charity than he knows what to do with. Somehow the city steps back from the precipice. Somehow nations continue to choose not to go to war again.
The people of the west have hidden themselves, taken shelter in basements and behind the high walls of the temple, but come out when they hear the call of the bison. The rescue squadrons got there in time. Almost all of the nation will live. The last foot has barely left the ground when the walls come down and the last refuges are swarmed by their attackers, but it doesn't matter. They can be nomads once again. He'll need to keep going to find enough food for this many people but that's okay, he has been solving this problem his entire life. It's a good problem to have.
