Schala

Schala is Queen Zeal's daughter in 12,000 B.C. in Chrono Trigger. She was the original owner of the pendant Marle had at the beginning of the game.

Beyond the Ruins
When Crono's party arrives at Zeal Palace, they find out that both Zeal's children, Schala and Janus, secretly oppose their mother and are against what she is doing with Lavos' power.

After powering up the pendant with the Mammon Machine, the party follows Schala into the Queen's chambers, where Dalton sics Golem on them.

After Crono's party defeats Golem, they are imprisoned by Zeal, only to be rescued by Schala and Janus. The Prophet means to kill Crono's party, but Schala wants their lives spared. So they all travel back down to the Time Gate on Terra Continent, send Crono's party through it, and the Prophet forces Schala to magically seal the Gate for good.
