Hopefully I'm not changing the topic too much, but something's been bugging me about the Black Omen recently, so I'll ask here.
So we've got the Black Omen in multiple time periods. If Chrono & Co. enter the Black Omen and eliminate Lavos in, say, 1000AD, does that destroy the Black Omen in 12,000BC and 600AD? I think the Compendium's official timeline assumes Chrono & Co. enter the Black Omen in 12,000BC and wipe out Lavos that way, which naturally takes care of the Omen in all later time periods.
I suppose the answer depends on where exactly the Black Omen draws its power from. Does it draw power from the Pocket Dimension, i.e., directly from Lavos? In that case, no matter when Lavos is defeated, the Omen would lose its power source and crash in 12,000BC.
Regarding how the Black Omen works temporally, I think you can fight all the bosses and Queen Zeal up to four times if you enter the Omen in 2300AD, 1000AD, 600AD, and 12,000BC in that order. Can anyone confirm this offhand? And I think if you defeat Lavos' shell through the Omen in 2300AD and go through the Black Omen in 1000AD, etc., the shell will already be destroyed for you, which is consistent with the Pocket Dimension having its own linear timeline separate from the world timeline.
