New zone found in Coerthas?

Found an NPC i think it was at 10,11 Coerthas. She said nobody who wasn't made allowed by the holy whatever may enter so i ran down anyways (bombs everywhere) where i'm dead is where it wouldn't let me run further as if there was an invisible forcefield. Anyone else been here? Seems like one of those zones where it doesn't load but music and everything changes.

There's several of these areas throughout eorzea, not sure if they're zones or dungeons or w/e.

Theres one up north east of Camp Iron Lake in La Noscea, and theres a few out in uldah.
