The sealing structure interlocks in the tiniest fractals. It is still being debated who or what caused the Dwemer to disappear, as well as whether they disappeared all at once or over a long period of time. In 1E 700, during the Battle of Red Mountain, for reasons still debated and under circumstances still under investigation, the Dwemer seemingly disappeared. The Dwemer are known for being the subjects of one of the greatest mysteries in all of Tamriel. They are well known for their skill and revolutionary developments in technology, engineering, crafting methods, metalwork, stonework, architecture, city-planning, science, mathematics, magic, and the academic arts. The Dwemer were an advanced race and civilization, in many respects far ahead of the other races and civilizations of their time. Mer used the term 'Dwemer,' roughly translated as 'People of the Deep.' The term also connoted 'deep-delving,' 'profound,' and 'close-counseled.' Men commonly refer to them as 'Dwarves,' in reference to the fables of the Giants seeing them as small.
The Dwemer (also referred to as the Dwarves, Deep-Elves, Deep Folk, Deep Ones, People of the Deep, Deep-Counseled or Secretive People or the under-Elves) were an ancient 'Lost Race' of Mer who were remnants of the early Aldmer, and lived primarily in the region of Dwemereth.
