The sandbox building title, Landmark, which was slated to serve as the building blocks (almost literally) for the now cancelled EverQuest Next, will itself close next month. If you followed and understood that verbal diarrhea of a sentence, you're a better person than I.

Yes, Landmark will close down on February 21, roughly six months after it was "launched." The voxel building sandbox title has been in development limbo for numerous months now after the fate of EverQuest Next was decided last March.
To the Landmark community,

With heavy hearts, we are writing today to inform you that after much review, we have decided to close Landmark game servers on February 21, 2017.

Since Landmark first entered Alpha, we have been impressed by the creative talents in this community. You pushed the boundaries of what Landmark could do, and we are grateful for the time and energy you shared through your creations in this game.

While there is still time to enjoy Lumeria and the many worlds you’ve built within Landmark, we wanted to let you know what you will be seeing happen between now and February. Beginning today, Player Studio items will no longer be available for listing or for purchase in the Landmark Marketplace. Landmark will also no longer be available for purchase. All items in the Marketplace with a Daybreak Cash price will have their price reduced to 1 DBC.

The game servers, as well as the accompanying forums and social media channels, will be closed at 4:00PM Pacific Time on Tuesday, February 21, 2017.

We want to thank each and every one of you for your creative contributions to Landmark.

Daybreak Game Company

The idea to give the rights to the game to someone else was considered but it seems as though Daybreak Games has already scrapped that idea.
What happens to all the code/data from Landmark? Can someone open an emulator server for Landmark?

Daybreak Game Company will retain all of the code and data from Landmark. Daybreak Game Company will not license or authorize the operation of a Landmark emulator or a fan-operated Landmark server.

If you happen to still have Daybreak Cash on your account, the studio says that you can use that to purchase items in other Daybreak games. If you don't play those, you might just be SOL.
