The last remaining areas or surrounding islands currently inaccessible in Eorzea

The Farreach

The Farreach is the homeland of the Hellsguard clan of Roegadyn. A volcanic, coastal region of Abalathia's Spine, it is known to be a harsh region constantly battered by gale-force winds blowing on the Bloodbrine Sea. (Could it be possible The Farreach is being planned as part of a expansion? I can see it being part of a expansion involving all the Roegadyn homelands)

The Pearl

An Island to the east of Aldenard located within the Rothlyt Sound. Coeurls are raised here by a handful of tamers living in recluse. The feral versions found in Eorzea are descendants of the war beasts that were once trained here. (it could be possible it might end up being planned later as part of a Beastmaster Quest)?

Mazlaya

The island of Mazlaya is situated in the southern waters of the Rothlyt Sound, directly to the east of mainland Aldenard and south of the Pearl. Little information is given about the island; Mazlaya is best known for being the home of the Dodo, a large, flightless cloudkin introduced to Aldenard by the Qiqirn. The Mazlaya Marlin, a fast-swimming fish which dwells in the Sea of Ash, is named for the island, and sea cucumbers found in the shallow waters around Mazlaya are prized as delicacies in the Far East.

A counterpart to Mazlaya exists in the First off the coast of mainland Norvrandt, but is not named on any in-game maps.

=======================

Currently the Cieldalaes is the latest addition, but I wonder if these areas listed above either are planned at some point or did the devs forget about the last pieces of Eorzea?
