Skirmish on P8X-412Edit
SG-1 and Vala Mal Doran travel to P8X-412 to try to convince the people not to embrace Origin. There during a trial for Vala called a Mal Doran, a Prior who used to be The Administrator of the village of Ver Eger in the Alteran Home Galaxy arrived. Daniel argued with the Prior about Origin and the Prior left giving the villagers time to make up their minds, but not before touching one of the villagers on the head and infecting him with the Prior plague in order to force the villagers to either decide to embrace Origin or die. Lt. Colonel Cameron Mitchell got infected and Vala used a Goa'uld healing device to try to cure the disease, but the virus mutated and the healing device became useless. Dr. Carolyn Lam tried to find a cure, but failed to do so. One of the villagers died before the Prior returned. A distraught Vala attempted to kill him with a FN P90 Personal Defense Weapon, but failed as he protected himself with telekinesis. Before the confrontation could escalate, the villagers accepted Origin and the Prior cured everyone of the disease including Mitchell and revived the dead villager. The Prior let SG-1 and Vala go so they could spread the word of what had happened there. (SG1: "The Powers That Be")
Skirmish on P9G-844Edit
In an attempt to cure the Prior Plague, Lt. Colonel Cameron Mitchell, Dr. Daniel Jackson and a couple of SG teams traveled to P9G-844, the Sodan homeworld, to try to capture the Prior that visited that world in order to obtain his blood believing that it held the key to a cure. Bringing the newly finished Prior disruptor with them, they convinced the Sodan who'd decided to turn against Origin to help in the capture and buried the Prior disruptor in the ground and Lord Haikon and Jolan lured the Prior into the circle where it was buried. Mitchell confronted the Prior while Daniel tried to find the correct frequency on the device to block the Prior's powers and managed to succeed as the Prior telekineticly chocked Mitchell. Mitchell then shot the Prior with a Zat'nik'tel, knocking him out. They then took the blood and attempted to convince him to change sides. They even brought in Orlin, a formerly Ascended Ancient who knew the Prior Damaris' past to convince him, but they failed and the Prior regained his powers and pulled Major General Henry Landry to him and began chocking him while infecting him with the Prior Plague. Mitchell then killed him from behind with a pistol while he was distracted. (SG1: "The Fourth Horseman, Part 2")
Skirmish on P9C-882Edit
In a debriefing, SG-1 learned that the planet P9C-882 had recently been visited by a Prior and that he would soon return and destroy the village if an Ara is not constructed. Major General Henry Landry informed the team, Lt. Colonel Samantha Carter in particular, that Arthur's Mantle could be used to hide the entire village. However, after only a short time the devices power source fails and the village was left unprotected when the Ori warship arrives in orbit and the Ori Army landed.
Armed with FN P90 Personal Defense Weapons, the villagers, as well as most of SG-1, defended the village from the Ori warriors. However, ultimately it was a losing battle. As ammo ran low, and several had already died, the skirmish quickly came to an end, and the Ori emerged victorious. It wasn't until later that Carter managed to get the device working again, protecting the village from destruction via an Ori energy beam weapon from an Ori warship after the Ori forces had left the planet.

SG-1's capture of AdriaEdit
After a very complicated plan, including implanting of false memories with the Galaran memory device, SG-1 captured Adria in her search of Clava Thessara Infinitas. SG-1 ambushes them with Prior disruptors to stop Adria from using her powers. However, Ba'al's Jaffa beam in and kidnap Adria. Ba'al later killed most of his clones and their Jaffa to make sure his plan was not ruined by them and their egos. He then implanted Adria with a clone while in the meantime SG-1 beamed aboard to retrieve Adria, but, unknown to them, it was actually Ba'al in control. They were successful in reaching Adria/Ba'al by killing several Jaffa and a Ba'al clone. But they soon realized it was not Adria but Ba'al. They devised a plan to swap Ba'al out for a Tok'ra but this plan failed when Ba'al released a symbiote toxin into her system in attempt to kill her so that the Tok'ra could not retrieve the knowledge she possessed.
Ba'al was extracted but not soon enough for Adria to use her Ori telekinetic powers to lock herself in. She begins preparations for ascension, while Lt. Colonel Cameron Mitchell and Teal'c attempt to cut their way in, but are distracted when Adria releases coolant into the corridor where Dr. Daniel Jackson is trapped. Vala Mal Doran attempts to kill Adria with one of the guard's guns, but is lifted into the air by Adria's telekinetic powers, allowing her to complete the ascension process uninterrupted. (SG1: "Dominion")
Skirmish on DakaraEdit
On the ruins of Dakara, SG-1 was searching for the Ark of Truth. When they found a box (which wasn't the ark), a group of Ori soldiers, commanded by Tomin attacked. Lt. Colonel Cameron Mitchell and Lt. Colonel Samantha Carter opened fire at them, but were outnumbered and surrounded. Tomin assured them that they would not be harmed if the surrendered. They agreed and allowed him to enter but he was followed by a Prior. Dr. Daniel Jackson tricked the Prior into opening the box but it only contained old papers that disentigrated when touched. The Prior ordered Tomin to kill them but he refused and Mitchell convinced him that the Prior was powerless. The Prior reached for Tomin's Ori staff weapon but Mitchell was able to grab a staff weapon himself and kill the Prior. Carter then showed Tomin a Prior disruptor, which neutralized the Priors' powers. After seeing the Prior killed, Tomin and the army surrendered. (SG1: "The Ark of Truth")
