Signet ring overview
A signet ring was a ring with the mark of an emblem or symbol on one end.

The Doctor kept a signet ring, which he frequently wore in his first incarnation. (TV: An Unearthly Child, et al)

Erimem wore a signet ring with the symbol of Sekhmet. (AUDIO: The Bride of Peladon)

The Master had a green signet ring with Gallifreyan writing which was used by the Disciples of Saxon to revive him after his death. (TV: The End of Time)

Finished-ish Key 2 Time edits
While on a rainy planet with Peri, the Doctor had discovered a compass, which was actually a segment of the Key to Time, from one of the derelict ships, The Green Man's Burden. After time was frozen on this planet, a sentient tracer sent by the Grace to collect the Key brought the TARDIS off course here, asking the Doctor if he could help her collect two more segments of the Key, which had been decaying after the Doctor put it together the previous time. The tracer turned the first segment into its original form and put it into a satchel leading to another universe.

Arriving on Mars in the distant past, the Doctor decided to name the Tracer "Amy", thinking she had agreed upon the name. Amy realised the segment of the Key was disguised as a capstone on the pyramid in the town. The Doctor and Amy were arrested and taken to Magistrate Isskar, accused of being thieves by Isskar's beadles. They were let go with a warning not to approach the pyramid. Understanding but disobeying the warning, inside the pyramid, the Doctor and Amy met another tracer whom already had one of the segments of the Key in her possession, along her assistant in her quest, Harmonious 14 Zink. The Tracer agreed to the Doctor's suggestion of "Zara", "just to shut you up". At the top of the pyramid, Zara touched the segment and turned it back into a crystal. This caused a gravity well to appear, causing massive changes to Mars' environment. Zara left with the segment using Zink's time ring. The Doctor, Amy and Zink jumped on board an approaching ship, and the Doctor piloted it to safety. Unable to help the catastrophe inflicted on Mars, the Doctor and Amy left in the TARDIS for their next destination.

The Doctor and Amy arrived inside a castle on the ring world of Safeplace about 16,000 years later. At a castle there, there was a succession dispute between the Valdigians, Lady Mesca and Wembik. The Doctor concocted an anti-venom for Mesca, whom Wembik had poisoned because she refused to allow Mesca's son to become king.

Meanwhile, the Ice Warriors, led by Isskar, now an Ice Lord, were guided to Safeplace by Zara to find the next segment, and began fighting the Valdigians. When the Ice Warriors were repelled, Amy worked out a compromise between Mesca and Wembik — they agreed to be married to one another, so that whoever's son became king, he would also be the son of the other one. While the Doctor asked Isskar to speak to him, his men brought Amy outside the castle grounds.

Zara spent generations manipulating the Valdigians as well as the Ice Warriors. She realised the castle was the next segment and turned the segment into a crystal, trapping the Doctor, the TARDIS, the Valdigians and Isskar inside. The Doctor struggled to hold on, before Amy, having received the segment in her battle with Zara, turned the segment back into a castle, allowing the Doctor, the Ice Warriors and the Valdigians to escape; the Ice Warriors took the TARDIS outside. Amy then turned it back into a crystal and placed it into her satchel.

The Ice Warriors took the Doctor and Amy onto Isskar's ship to take them a tribunal; Isskar confiscated the segments and sent the TARDIS overboard while the ship was in hyperspace. Zara, being unable to detect Amy's segments, travelled back in time with the time ring, having "wrecked the controls" of the ship. The ship was on a collision course with the red giant, Leboon. When the last escape pod was taken, leaving the Doctor and Amy behind, the Doctor tried fixing the ship, before the Black Guardian intervened, telling the Doctor that he hoped the Doctor could explain the situation.
