After this accident, they decide to enjoy the fair together, they head to check out Lucca, Crono's friend and inventor by trade, as well her next invention, an teleporter of some kind.
When Marle tries out the teleporter, something goes wrong, and she is warped somewhere else. In order to save her, Crono doesn't hesitate to replicate the conditions that caused the warp to pursue her, with Lucca's help.
The next thing he knows... he finds himself in another place, which he eventually learns to be the past, in the year of 600 AD. There he finds Marle at Guardia castle, but she dissapears shortly after.
Lucca suceeds in following Crono in the time warp and explains to him that Marle's ancestor in this age might be in danger, as Marle is none other than princess Nadia from their time. The potential death of Queen Leen would cause Marle to cease to exist.
