Nirrti's attack on Hanka and Earth was an event that took place on Hanka and Earth in 1997 during the Tau'ri-Goa'uld War.

Battle[]

SG-1 travels to the planet Hanka to watch a black hole through an eclipse only to find the entire population and SG-7 dead. SG-1 call in a medical team led by Dr. Janet Fraiser who determine that the population was killed off by a bacterial infection. SG-1, while tagging the bodies of the villagers, locate one survivor, a little girl named Cassandra. Frasier determines that the entire planet has been infected with the bacteria, with it in both the ground and water but not the air. She also determines that SG-1 aren't infected.

Captain Samantha Carter, Dr. Daniel Jackson and Frasier take Cassandra back to Earth and come to believe that they may have caused the deaths on Hanka which are determined to be 1,432 by one of SG-7 possibly bringing a normally harmless bacteria to the planet, it taking on traits from some organism there and then mutating into a very deadly strain of bacteria that killed everyone. As Cassandra seems to be immune, Frasier decides to run tests in hopes of finding a cure for other deadly infections on Earth though they can't figure out why SG-7 didn't report the outbreak. After Cassandra's heart stops and they are forced to restart it with an electric shock, Frasier discovers a strange sound when she listens to the girl's heartbeat and a chest x-ray shows a mysterious object in her chest near her heart. Frasier and Dr. William Warner do a biopsy, getting samples from the object, but are forced to stop the surgery when the object stops Cassandra's heart when they get too close to it.

It is determined that the object is made up of iron and potassium on one side and Naquadah on the other and that the layer between the two is slowly decaying and the two sides will eventually come together so Carter performs an experiment robotically in a lead-lined room in the SGC's subbasement to see what will happen when the two sides come together using microscopic samples of the two sides. The result is a massive explosion that leaves Gamma rays and particle radiation off the scale in the room. As a result, they realize that it's a bomb meant to destroy Stargate Command and the Stargate and the whole thing was a set-up from the beginning: the Goa'uld wiped out the people on the planet and kept SG-7 from warning Earth so that Cassandra would be brought back to Earth and designed the device so that it would create itself once on Earth with Frasier theorizing that them giving Cassandra iron supplements when she arrived may have helped create the device and that when they gave her an electric shock to restart her heart, it activated the device. After learning they have just under two hours until the bomb goes off and talking with the President, Major General George S. Hammond decides to send Cassandra back through the Stargate to Hanka so she is no longer a threat to Earth.

At the same time, on Hanka, while viewing the black hole, Colonel Jack O'Neill and Teal'c observe another object through the telescope that turns out to be a Goa'uld Ha'tak ship. Teal'c identifies it as belonging to the Goa'uld Nirrti and figures out the plot based on past experiences: Nirrti once sent a peace emissary to a planet that was contested between her and Apophis, but when the emissary reentered the Stargate to go home, a massive explosion happened that destroyed the Stargate. Teal'c realizes that Nirrti intends the same on Earth using Cassandra and she thus can't be allowed to go through the Stargate. Under attack from Goa'uld Death Gliders, O'Neill and Teal'c manage to dial the Stargate and make it through to Earth just as on Earth they were about to finish dialing the Stargate to Hanka and send through Cassandra who falls into a coma upon approaching the Stargate. O'Neill and Teal'c prevent Cassandra from being sent through and to protect the SGC.

SG-1 takes her to a nearby abandoned nuclear facility to safely explode. Carter takes Cassandra deep underground, but after she wakes up, can't leave her. Cassandra doesn't explode and Carter reveals she realized that Cassandra's proximity to the Stargate was causing the bomb to grow and then explode. Once she was far enough away, the bomb wouldn't detonate anymore. Eventually, the bomb dissipates and is absorbed into Cassandra's system and Frasier adopts her. Later, the SGC sends a team back to Hanka and they cremate the bodies of those who died of the infection. Four years later, when Cassandra starts to go through weird changes, SG-1 returns to Hanka to find that the bacteria is gone and that Nirrti had another reason for wiping out the population: she wanted to hide her experiments to create a hok'tar which were at risk of being exposed with the presence of SG-7.^[3]
