Post your speculations on where you think future coil areas or turns might be located.

I have a few here. The Burning Wall in Eastern Thanalan (there are what looks like Allegan ruins among some of the crystals)

The area around X15:Y31 in North Shroud (more Allegan stuff [around where the floating rocks are])
The red area in Boulder Downs in Coerthas Central Highlands (There is what looks like part of an Allegan structure that juts out of the ground there)

If anyone has more speculations based on the places they've seen, post it here
