Attempted kidnapping of Avatar Korra

The attack on the Beifong Estate, in Zaofu, was a confrontations that occurred a few weeks after Harmonic Convergence of 171 AG between Avatar Korra and her allies and Zaheer's gang. The two groups engaged in a battle to decide the fate of Avatar Korra, which eventually ended with parts of the Beifong Estate damaged and Zaheer's gang failing their mission, but successfully escapes.

Prelude
In 158 AG, shortly after Korra was discovered to be the Avatar, Zaheer and his gang attempted to kidnapp Korra, however their attempts were thrawted by Chief Sokka, Fire Lord Zuko, Tenzin, and Tonraq. They were later placed in special prisons designed by the White Lotus to detain their bending abilities, and were constantly watched by White Lotus sentries. Zaheer's Prison was high up in several mountain ranges, Ghazan's Prison was in the middle of the ocean, Ming-Hua's Prison was in a volcano, and P'Li's prison was in the western tundras of the Northern Water Tribe.

In 171 AG, after Harmonic Convergence, Zaheer became an airbender and broke out of his prison before freeing the rest of his gang. Lord Zuko was alarmed by this revalation and travelled up to the Northern Water Tribe to meet the new chiefs Desna and Eska and Chief Tonraq. There they went to the Western Tundra to make sure that Zaheer and his gang would not free P'Li. However, after a brief battle, the gang manages to defeat Lord Zuko, Tonraq,Desna and Eska, freed P'Li and retreated to Republic City.

There, the gang took refuge in a vine habitat, and Zaheer goes to Air Temple Island to find the Avatar under the guise of Yorru. There, he trainned in airbending for a short period of time before getting caught by Kya in Tenzin's study. After a brief talk, Kya attacks Zaheer, which he attempts to flee Air Temple Island. His attempt was successful as he defeated several firebending White Lotus sentries, and Kya. The gang then realises they had to retreat Republic City as the Republic City Police Force was on the hunt for the four of them. SO they blackmailed a ride from a delivery man to get out of Republic City. Their plan was successful and they left Republic City.

Zaheer later meditates nearby the gang's campfire to figure out where the Avatar was. He found out that she's in Zaofu. With the help of Aiwei, the gang manages to get into Zaofu by nightfall.

Aftermath
The battle ended with Zaheer's gang's failed attempt to capture Korra, and fled Zaofu. Parts of the Beifong Estate was damaged including their garden. Team Avatar, with the help of Varrick, discovers Aiwei's treachery to the Metal Clan, as he framed an innocent metalbending guard and attempted to kill the Avatar with a bomb planted in his secret room, which destroyed all evidence of his connections to Zaheer's gang. Team Avatar was given a jeep by Su, and leaves Zaofu to hunt Aiwei down.
