You could possibly get an overview on the patch below, via Square Enix:
Patch 3.35 introduces the Deep Dungeon: The Palace on the Dead, where newcomers and veterans can band together to have an unprecedented adventure in Final Fantasy XIV Gil. With parties as high as four, the Palace from the Dead may be the first of many planned content updates where players can battle by using an array of enemies, avoid traps and tackle bosses to achieve valuable experience. The dungeon features randomly generated maps, several dozen floors, and starts every participant at Level 1 having a unique new progression system. Diving deep into your dungeon will dsicover players working on strengthening their gear in their journey, because they work to unravel the mystery in the Palace with the Dead.
Detective Superintendent Paul Monk said: “As yet, we've not formally identified the particular groups but this is really a significant development and Sian’s family have already been informed.”
Police previously confirmed that Ms Blake’s car was discovered on Final Fantasy 14 Gil Calvert Avenue, Bethnal Green, in east London for the 3rd of January, however it’s currently unclear who left your vehicle there.
Finally, Detective Paul Monk said police officers are continuing to look for and find Mr Simpson-Kent.
