The Tanallay Surge complex was a major political and recreational hub on the Expansion Region world of Tynna. The seat of the Tynnan government, it was surrounded by water chutes and fountains and was several stories in height. During the Yuuzhan Vong War, the extra-galactic Yuuzhan Vong assaulted Tynna and landed at the Surge complex to begin a program of terraforming on the planet.
The Tanallay Surge complex was a legislative and recreational installation on the Expansion Region planet of Tynna, and the seat of the Tynnan government. It was several stories high, spread out over a large area and fronted by a wide set of steps linked to a picturesque lagoon. Surrounded by many pools, water chutes, and fountains, the complex was the site of the Tanallay Surge posting agency, a posting agency frequented by bounty hunters.

During the Yuuzhan Vong War, in 26 ABY, the extra-galactic Yuuzhan Vong attacked Tynna, defeating its meager defensive contingent of starfighters, and made planetfall at the Tanallay Surge complex. As they did so, an unarmed group of several hundred Tynnans—tricked by the collaborationist Peace Brigade into surrendering Tynna to the invaders without firing a shot—awaited the landing force at the main steps above the lagoon.
The Yuuzhan Vong force led by Supreme Commander Nas Choka and Commander Malik Carr, however, had no intentions of meeting with the Tynnans and left them to wait at the Surge complex. In the meantime, the Yuuzhan Vong began the biological engineering of Tynna's oceans, releasing a chemical from their dropships to optimize the water for the cultivation of biots such as dovin basals for use in their further conquest of the galaxy. These events were witnessed by a New Republic stealth ship as they were broadcast via satellite to every city on Tynna.
