- "Icon" is the 5th episode of Stargate SG-1 Season 8.
- In a bedroom 50's fashion-like, a woman is taking care of a lied wounded man with a bandage all around his eyes. She removes carefully the bandage, revealing Daniel Jackson. Jackson, whose face still has traces of wounds, eventually open his eyes, focusing on his caretaker, Leda.
- When Leda tells Daniel that he is in a house that belonged to her uncle miles away from the city, he remember that many people died may be because of them. Leda reassures him and says that to see him alive is quite a miracle.
- Three months earlier, inside a museum, a guide is making a tour of all the artefacts found during archeological diggings, and ends on the masterpiece found in the Kirellian wastelands 150 years ago; the Great Ring of Avidan—which is revealed to be a Stargate.
- While they go outside to see the ring in a closer view, the guide tells them that, according to the local researchers, it is several thousand years old at least, and may be built by the ancients inhabitants to honour their gods.
- As he continues to describe the artefact, the Stargate activates, much to their very surprise. After the kawoosh, an Earthling MALP exites the wormhole. The two guards present here aim their guns and start to check the vehicle.
- Later, an official welcome comity replaces the museum's visitors. The Stargate is open and Lieutenant Colonel Carter, Teal'c and Doctor Daniel Jackson come out the gate. Commander Gareth greats them in the name of the people of the Rand Protectorate. Carter apologizes about the tourists as for her, this is the first time they travel through a "museum piece".
- Gareth wonders about the purpose of the Stargate, and Jared Kane, Gareth's chief aide, wonders about the fact that their visitors are human, like them. Jackson and Carter tell them that they will explain later the reason they are human. Jackson notices the impact of the "Great Ring" in the local culture. Kane tells them that in old times, powerful gods were master and they think that the ring was their source of power. Yet, even if according to Gareth, these are legends, some people who follow the old ways may see SG-1's arrival concuring their beliefs.
- Present day, in Leda's house, Leda begins to clean the Jackson face's wounds while he's sleeping, but she wakes him. She's giving him a small dose of pain killer as all the medicine is in short supply. When she wants to leave to let him rest, Jackson asks her to stay.
- Two months ago, in the Stargate Command briefing room, Jackson reports to Brigadier General O'Neill that his time with the Caledonian Federation's representatives was limited for Gareth had security concerns about revealing to much about the Stargate. As O'Neill guesses, the two nations are in a cold war for decades, with weapons on both sides able to wipe out the entire planet. Jackson mentions that there is a group of religious foundamentalists led by a man named Soren, who believe that the planet's live has been created by the gods and that the co-called gods will return and reward them for their faith. SG-1's arrival through a public Stargate comfirmed their beliefs and now, their numbers are growing. O'Neill agrees with the danger of the situation, yet tells them that this is not their concern.
- Later in the SGC corridor, Jackson tries to convince O'Neill to let him return to Tegalus so he could explain the truth about all of this. O'Neill warns him that the situation may aggravate. O'Neill reluctantly agrees yet he order Jackson when "the second things are going squirrelly", he has to come back.
- On Tegalus, the Stargate is called the "Great Ring of Avidan", and is part of a mythology.
||When the Stargate is activated at the moment of the arrival of SG-1 on Tegalus, the Glyph representing Earth is visible at the lower right of the gate. As this symbol is Earth's point of origin, it shouldn't be present on the Tegalan gate.
