This is almost what i think will happen or should
Actually wrote this out for the last thread but thought i would fit it in here for you to check out
New playable race :Maormer(http://elderscrolls.wikia.com/wiki/Maormer)
new continent/land mass

yandonea(http://elderscrolls.wikia.com/wiki/Pyandonea)
New mounts: sea serpent/creatures (water based) for transport between areas of the Pyandonea island mass
New dungions and quests:underwater caverns leading to interior island caverns
main quest extention: A message from a unknown sorce arrives by carrier stating that the dragonborn is required in a land far away the Pyandonea islands are under attack by Sanguine as he has descovered that the island is likely to hold many secrets involving ancient artifacts that could tear Nirn in 2 if used or in the his hands
the DLC would include a quest into Sanguine realm of oblivion for a battle to close his entrance into Nirn
the phyjjic order meet the dragonborn in pyandonea to create a deverse plan to reclaim the artifacts of the 8 original divines that bestowed the life energy of themselves to create Nirm on the godly artifacts known only as the (tools of creation)
Sword :judgement
Shield: protection
armor The savior
bow: direction
axe: Consequence
Boots: Initiative
Gloves:Hand of gods
Helmet: Redemption
The items are then placed in a box in a shrine of the 8 divine
the shrine changes the items into a artifact of the divine gods that is used later to close the grasp that sanguine has on Nirn forever
1 Item for each of the gods
the dungeons are
6 on the new land mass and 2 in the north western region of tamriel (small portion of upper north western map of skyrim )
each of the dungeons are completely hidden and some require using a shovel to find the entrance
New magics (water and serpent based)
spell creation
mage portals conjured by the player to travel to and from skyrim and pyandonea
New players using the new race start in Pyandonea and get a vision to go help in skyrim as the dragonborn
the player awakes as a prisoner same plot as the usual skyrim questline once in skyrim
as a leveled character you will just be contacted in game by a courier
let me know what you think and add what ever you like just some ideas about a area that has yet been seen in a very long time in Nirn history
