After Lavos crashes in 65,000,000 BC, one of the Ioka villagers state that he found a weird red stone, but said it was warm, so he dropped it. Sounds to me like the Frozen Flame, espically since being as Ayla was given the Dreamstone in recognition of her being a chief, it must be rare, a mineral mined from the earth. Meaning if he found it on the ground, I can see how it's not Dreamstone, but the Frozen Flame. Plus, he wasn't corrupted because Lavos was still weak from the crash.
