Known as the first tribe to feature a turning of tides, the post-merge was marked by the dominance of formerly unaligned castaways joining forces to take down their rivals.

Soliantu was created when Kathy Vavrick-O'Brien of Maraamu, and Rob Mariano of Rotu met on Day 21. The tribe started out being controlled by the Rotu Four alliance of John Carroll, Robert DeCanio, Tammy Leitner, and Zoe Zanidakis. After arguments involving Rob and John, the Rotu Four targeted Rob. Kathy won the Immunity Challenge, and decided not to give it up. At the first Tribal Council, the alliance, along with Neleh Dennis, Paschal English, and Vecepia Towery voted for Rob, eliminating him from the game.
Sean Rector, Rob's ally was infuriated by the vote, and wanted to target John. Sean already had Kathy with him on the outs, as well as Vecepia, who apologized for voting Rob. Even after some convincing, Neleh and Paschal still stuck with John's alliance until the Immunity Challenge. At the challenge, the alliance flexed its muscles and first eliminated Sean, with Kathy and Vecepia following. They then targeted Paschal, followed by Neleh. After Tammy won the challenge, Neleh and Paschal realized they were fifth and sixth in the pecking order if they went with the Rotu Four. After the challenge, they approached Sean and agreed to vote with him against John. At the Tribal Council, the Outsiders Alliance came through, and John was blindsided in a 6-3 vote.
After John's elimination, the other members of the alliance were on the bottom. Zoe tried a last ditch effort to save herself by separating herself from Robert and Tammy. Tammy won immunity again, and Zoe's plan failed as she unanimously became the third victim of the Soliantu tribe. After Zoe was voted out, Robert and Tammy were desperate. Robert tried to catch a pig to provide food, and Tammy tried to win a third consecutive immunity. In the end, Robert won the Immunity Challenge and the alliance voted out Tammy.
As Robert became the last member of the original Rotu Four, the Outsiders Alliance realized they would soon have to turn on themselves. At the Immunity Challenge, Robert desperately needed a win, but instead, Vecepia won it. Kathy considered getting Robert, Sean, and Vecepia to vote against Neleh and Paschal, as they were seen as the biggest threats. However, that did not materialize, and Robert unanimously because the fifth person eliminated from the Soliantu tribe.
Now that the Rotu Four was extinct, the Outsiders Alliance had to turn on itself. Sean and Vecepia were trying to oust Neleh, while Neleh and Paschal were trying to oust Sean. The swing vote came down to Kathy. Kathy ended up winning the Immunity Challenge, which influenced Sean to try and make a deal for it. Unfortunately for him, Kathy sided with the other two and voted him out.
As the last days of the game approached, Vecepia realized if she did not win the next Immunity Challenge, she would be voted out. Fortunately, she won immunity, making Kathy a target. Kathy made a deal with Vecepia, and the two decided to vote Neleh. Neleh and Paschal tried to vote Kathy. After a deadlock tie, rocks were passed out, and whoever drew the purple rock was eliminated. In the end, Paschal drew the rock, and was voted out.
At the Final Immunity Challenge, Kathy was the first to drop out. Neleh knew that she needed to win or she would be voted out. Eventually, Vecepia ditched her deal with Kathy and made a new one with Neleh, and allowed Neleh to win immunity. At Tribal Council, Neleh stuck to her word and decided to go to the end with Vecepia, as she voted out Kathy.
