Hey, guerin, welcome to the Compendium. Hoped you liked Chrono Cross. It is indeed very confusing, so I'll try my best to answer your questions. I'll start with the 3rd question, since it's the easiest.
3)where is lady riddel of the homeworld? we only ever anotherworld's riddel.
Riddel of Home World perished along with the other Dragoons at the Dead Sea,
as seen by this picture. From the looks of it, Riddel, Glenn, the 3 Devas, and General Viper were all there. On to question 2!
2)in the very beginning of the game, when the huge wave washes over serge and sends him to the other world.
who does this to him? and how did he do it?
That's a good question, something I've always had a hard time making heads or tails of. The ghost of Lucca tells us at the end of the game that Kid did it. In other words, during the timeline in which Serge died (before Another World and Home World split), Kid traveled back in time to 1010 AD to save Serge (thus splitting the dimensions [
somehow]),
and she later calls Serge into Another World while he is talking to Leena at Opassa Beach. In the first instance, she probably used one of Lucca's Time Eggs or one given to her by Belthasar. In the second instance, Kid (the one from the now-new Another World
***, mind you) probably used her Astral Amulet. Maybe someone else could explain better. Now for question 3.
1)so basically everything that happens in the game is actually balthazar's plan to save his friend schala, right?
iirc, even the whole thing about schala hearing serge's crying after he was attacked by the panther was balthazar's doing.
so the question is, why serge out of all people?
before serge became the arbiter, there was absolutely nothing special about him, why did balthazar choose him for his plan?
how did he even know who he was?
(note: if my memory is mistaken, and schala's creation of the storm that led to serge's becoming the arbiter was NOT influenced by balthazar, then my question was answered)
Yep. Belthasar planned it all. His "Project Kid" was designed for one purpose: to get Serge the Chrono Cross so that he may save Schala. My details are muffled, though, on just how much Belthasar knew what would happen. For example, I do not know if Schala's intervention was planned. In fact, I do not know if even Belthasar knew Serge would be the Arbiter. However, given the ridiculously ridiculous
Xanatos Roulette going on here, you can pretty much dumb down nearly every misconception in the game to "Belthasar did it."
Hoped I helped solve some mysteries for you.

***Could someone explain why the Kid from Another World doesn't get Time Bastard...ed... because of the original Kid's time travel to the past?
