Cuttlefish That Loves Diving
We know Fors gave us the clue that Madam Piers is not of the 22 Sequences already known. We know that there are 9 Outer Gods outside the planet ( 1 probably sealed in the genie lamp - Son of Chaos ) 6 paths are corrupted. That means that of the rest of the 6, a few of them tried to find another way to corrupt ( Because the only good thing Amon did, was prohibiting them to invade ). That means, there are others outer paths there, and I think COI made another of fate and time type.
