Don't make the same post over... We already have one topic going about the pendant >.<
This just gets confusing. But ill add some of my opinion anyway, which is in the other topic anyway.
1. Marle and Schala's pendant is of the same origin, but from different time lines. Marles is one that went though the whole Lavos Timeline yup to the Telepod and there it was triggered by the Entity. Marles pendent HAS NO POWER IN IT!
2. Schala's pendant is Marle's pendant in the Lavos Timeline, but in 12,000BC her pendant is fully charged. In Crono's time line, Schala's pendants last powers are used to teleport the gang out of the Ocean Palace, whilst in the Lavos time line should have been used to teleport herself out.
My theory goes on to believe that as Schala was sucked into the mammon machine, her pendant was recharged and then she ended up in the DBT, waiting for Lavos. When the time came, she was in the process of fusing with him. He was putting his negative thoughts into her. To keep her sanity, she used some of her pendants powers to clone herself and send Kid out through time, close enough to 1000AD. With Kid, the pendant came, but it was still charged, having the power to turn back time a little if Kid was in a life threatening situation.
3.Kid seems to have two pendants. The Astral Amulet, thought to be a pendant with the incomplete time egg. Since I don't believe that there is a wooden Schala's Amulet, I believe that the Astral Amulet is wooden, and that there was a translation error. This Astral Amulet allows Serge and crew to travel between Dimensions.
Whilst the pendant that Kid may have somewhere on her, unseeable or it being the pendant on her neck, but with extra shells for decoration on it; this pendant was Schala's, but was sent with Kid through time. It safeguard's Kid so if she is in a life-death situation, she will be transported into the immediate past.
My hand hurts now..
