Have we seen a dyad in the Force before?

Question

In The Rise of Skywalker we find out that the connection between Rey and Kylo is a bit more than what we first though. They form a dyad in the Force: a pairing of two physical beings that become one in the Force.

Kylo Ren: My mother was the daughter of Vader. Your father was the son of the Emperor. What Palpatine doesn’t know is we’re a dyad in the Force way. Two that are one. We’ll kill him together and take the throne.

_{The Rise of Skywalker}

Later on we learn of a prophecy about this dyad in the Force that was about restoring Emperor Palpatine to his former self.

Emperor Palpatine: The life force of your bond, a dyad in the Force. A power like life itself. Unseen for generations. And now, the power of two restores the one true Emperor.

_{The Rise of Skywalker}

What is interesting about this though is that Palpatine says "Unseen for generations" which indicates it has been seen before.

Do we know when a dyad in the Force has shown up before? If not have we seen any other Force-bonds similar to Rey and Kylo that could have been a dyad but it just wasn't named yet? (The Rise of Skywalker and its Visual Dictionary seem to be the first time it was identified as a dyad in the Force).

Legends answers are acceptable but I am mainly looking for canon answers.

Answer 1

The Jedi Exile Meetra Surik and Kreia had a particularly strong Force-Bond in the second Knights of the Old Republic game, which has many of the same features as the bond between Kylo and Rey seems to have.

Across vast distances, Kreia was able to contact Meetra and lecture her on whatever it was she was doing at that time, much like the way Kylo and Rey seem to be able to talk to one-another over large distances.

They never showed the ability to teleport objects, though, so if this was a Dyad or not is hard to tell, especially because a Dyad is something new that was made up for the new trilogy as a plot device to allow the characters to communicate without coming physically face-to-face.

It was always through the demands of the story. With the Force connections between Rey and Kylo I thought, “OK, I need to get these two talking. But if I put them face to face they’re going to either fight, or one of them has to be tied up” — Interview

So odds are any link you can find to old stories with a Force-Bond that feels like a Dyad in the Force is mostly just a coincidence, considering Rian Johnson made up the connection between Rey and Kylo as a plot convenience.

Answer 2

A canon example might be Luke & Leia themselves. Even in the original trilogy, they are able to communicate, as when Leia rescues Luke from Cloud City.

Luke: Leia. Hear Me.
Leia: Luke. We've got to go back...

Sure, they're not able chit-chat or send objects across the gulf (yet) as they're just starting out! Clearly, Luke has been able to communicate his location, which I think it is safe to assume that Leia has actually seen even though this is not revealed on screen.

Answer 3

Luke and Leia are force dyads. Not only can they sense each other... Leia sensing Luke in distress in Empire. But in The Last Jedi, Luke connects and transfers Han's dice. This lasts long enough for Kylo Ren/Ben to pick it up. At that point, it disappears.

Personal speculation, the object gets "reset" into it's original space the moment one or both halves of the dyad die. That would explain why the dice disappears at the same time that Luke dies.

Kylo Ren, figures this out and realizes that he and Rey are a dyad as well. This is why he knows that he can manipulate Rey's physical space while not present there physically. Hence the scene where he grabs the necklace. He's already seen what a force dyad can do because he found his father's dice.

Further personal speculation, Force Dyads can travel long distance as a result of their connection. The greater the connection, the greater the power of the two force users, the greater the chances that one can "teleport" to the other half's location. (of course, this would be in novelizations and further Star Wars media. But I'd like to think this is possible.)

BTW - even more personal speculation - force dyads must be dark/light. It's like a battery. Positive and Negative to push the force between the two "magnetic" poles. Luke is quite obviously a dark sensitive force user whereas Leia is a light sensitive force user. Luke is prone to anger and violence and fear. Leia is not as prone to fear as her twin brother.

I like the idea of a force dyad. It lends itself into the balance magic system of Star Wars.
