Stargate Infinity

After being chased by creatures and visiting an ice planet, the team begins to wonder if they are on a pointless quest. Draga opens a gate to ""where they wish to go"" and they end up on Earth in the Yucatan, where a local professor working for a Horace Van Gelder reveals she discovered the new gate. The shapeshifter Nephestus, disguised as Grimes, is working with Van Gelder and gets word the team is present when they contact Stargate Command. Disguised as Stoneman, Nephestus welcomes them and claims he'll help them clear their names, then summons Da'kyll and his Tlak'khan. Draga suspects something as Stoneman sends the cadets into Cancun – in fact it's an ambush but they turn around and return. Gus and Draga catch on and make their escape while the others return in just in time to rescue them. The team is forced to escape through the Gate and go on the run once more before they can clear their names, and the Tlak'khan and Nephestus depart with Van Gelder as Nephestus takes his place to

The team arrive on a desert planet in the middle of a sandstorm and meet Mashuma of the Mo'Tai people and his tribe. Seattle leads the group in helping the Mo'Tai find buried water and then finds an irradiated rock that could be used to power the pumps but Seattle soon becomes impatient to help and uses full power, setting off a quake but finding a huge energy rock and a energy sphere that unleashes memories for Seattle of how her father refused to admit his mistake in moving away from their home to the city. Seattle continues and is injured during an excavation but is more determined then ever. Another energy sphere escapes and heads for the village and Ec'co figures out how to trap it long enough for Draga to establish communication with the creature and determine its want to return home to the energy-rocks. Without the rocks, the team comes up with a way to use windmills to run the pumps.

The team find themselves on a plant of locals who worship and emulate the Tlak'khan but are suffering from a plague. Draga cures as many as she can but the leader, Mek'rod, insists they are the Tlak'khan and follow their ways, but eventually acknowledges the Tlak'khan merely provide them with help. Ec'co comes up with a cure for the plague while the Mar'dan elders summon Da'kyll and his men who tell the Mar'dan to obey them and lure the team into a trap. The Tlak'khan abandon the Mar'dan to the plague and Mek'rod turns against them. The team breaks free only to enter a trap, but the Mar'dan turn against the Tlak'khan and drive them off.

The team arrive on Octasar where a Dr. Carrie Mason of the SGC is working with a local scientist, Dr. Bri'sal, who is working on a project of universal telepathy as part of a scientific conference and believes the Tlak'khan can help him - they're playing him, naturally, since Bri'sal's fellow scientists don't support his project. Stacey overhears them while the rest of the team convinces Mason they're not traitors. Mason doesn't believe them and when the project succeeds the Tlak'khan take control. The team launches an attack but the mind-controlled scientists are forced to attack them, but Mason grabs Da'kyll's device, freeing everyone and forcing the Tlak'khan to retreat.

The team arrives on a civilized high-tech planet, Rokari, where they determine a comet is heading for the world they're on with only 60 hours to spare. The local government, the Commonality, don't believe their warning and state they have outgrown written and recorded language. The team break out a member of an underground resistance that distributes writing and leads them to a hidden library with info on how to use the planet's defense system. Harrison manages to figure out the language and the team activates the defense system, the Commonality sees the value of writing and everything turns out well.

The team arrive on a planet where the natives bear a extremely strong resemblence to Draga. They are contemptous of ""rock crawlers"" but Draga is drawn to them. But when the Tlak'khan show up the local's powers serve no good. The team helps them and gives them a measure of understanding of other cultures.

Gus and Seattle go into an alien VR system where the real society has deteriorated due to its preoccupation with the virtual one.

Gus brings the gang to Brianna for some rest and relaxation and they're caught in an earthquake. Harrison, separated from his jet pack, is rescued by Havave and helps him on his Kamuna initiation ceremony, while Ec'co discovers the volcano they are near will explode and destroy the local island. Harrison tries to convince Havave not to give in to peer pressure while helping him deliver an egg to a local creature as part of the rite, but they fail. He and Havene meet up with the others and the Akua, Havane's people. The Akua initially refuse to leave but Havane's actions convince them and they accept him despite his failure. The team manage to get to the Gate just in time as the island is destroyed.

The team arrive on a new planet and find diamonds. The team soon starts arguing over the diamonds themselves - a concept which Draga has trouble understanding. While Gus explains the concept of ""money' at great length, a team of bounty hunters closes in on the SG crew. Gus and Draga get captured but Gus turns the mercenaries against each other by playing on their greed. The team manages to overcome their greed and get it together to help out Gus and Draga but have to give up the diamonds to the mercenaries to buy their friends' freedom.

After avoiding a flash flood, Seattle finds a kitten-like creature that she names Flotsam. It gets into their food supplies and grows substantially...and grows some more. All efforts to train him seem in vain and it looks like the team will have to leave him behind. Da'kyll and his Tlak'kahn mercenaries show up and Flotsam gives warning by playing ""fetch"" with a grenade. A simlar flash flood wipes out the Tlak'kahn and Seattle agrees to leave Flotsam behind.

Arriving on a waterworld, the team makes for a nearby island after losing one of their vehicles while Da'kyll reports to Hah'lak that he knows where Draga is. The councilman sends a pair of bounty hunters after them behind Da'kyll's back. Ec'co, Draga, and Seattle get captured by the local amphibious natives and take the rest of the team to meet them. The locals, the Su'ri, welcome them once they are sure of the ""landers""' motives. The bounty hunters negotiate with Sargall, one of the younger members, to have him turn over the team in return for medicine. Driven by jealousy toward Harrison, Sargall helps the mercenaries by helping them capture Seattle to lure in Draga and then challenges Harrison to a dangerous race. While Gus tries to rescue R.J., Draga gets captured and Ec'co and Stacey give pursuit. Harrison rescues Sargall from a monster and then Gus leads the monster to the escaping mercenaries as they enter the Stargate without their captives and it ends up attacking a waiting Ha

When the younger team members reminesce about birthday's, Ec'co thinks back to his own torn life. The team convinces Gus to take Ec'co to his homeworld. An electrical storm shorts out their Stargate while Gus and Ec'co get taken into custody by the hostile Hrathi, who know of Gus' alleged betrayal. The rest of the team rig a way to recharge the Stargate using lightning while the Tlak'khan launch an attack on the Hrathi. Gus helps to drive them off and then are taken to a cache of data crystals. It turns out the crystals are a fake, but one of the Hrathi reveals he is a shapeshifter. Gus and Ec'co pass the test and receive the real Tlak'khan data crystal they need.

The team stay on a jungle planet, cut off by Nephestis who has framed Gus as a traitor. The local Thorn aliens are dying of a disease which Gus believes he left there on a previous expedition. The others choose to head out with the Ancient chrysalis but are ambushed by the Tlak'khan but escape...as the chrysalis hatches and the winged Ancient escapes. The Tlak'khan leader De'kyll takes the Thorn village hostage and Bonner surrenders but the Ancient intervenes and the cadets take them prisoner (except De'kyll escapes). The Ancient learns English through Seattle and asks the team for help, and after being named Draga. Draga heals the ailing Thorn but knows nothing about the Stargates and remains with the team.
