It's called Google, searched ff karnak and this was the third link: http://finalfantasy.wikia.com/wiki/Karnak
Karnak, originally romanized Karnac (カルナック Karunakku), is a location in Final Fantasy V. It is accessible on both Bartz's World and Merged World. It is located north of the Library of the Ancients, although any land access to it has been blocked by the huge wall that Queen Karnak ordered her people to build.
