The Dwemer survived?

[Rickious]

Apologies if any of this has already been discussed but I have a few suggestions which may or may not be possible.

• 1- I always thought a secret and vast underground network of Dwemer cities would add an amazing element to the game. Obviously this would be a full mod in itself. The Dwarves survived in deep, sealed underground cities all over Tamriel! Maybe some kind of portals to gain entry. And instead of keys, a full list of items which must be acquired to enter i.e. armour, jewellery. Some can be found, some self enchanted, but a fun and inventive list of dwarven items.
  
  For this mod maybe you only gain entry to a small area, an underground village which has been mostly abandoned apart from 1 elderly Dwemer druid/priest/mage who refused to leave and protected himself from whatever happened using magic but will tell the full story of the underground cities 'the young'uns' went off to build.
  
• 2- Even without going as far as the above. Maybe put the occasional hint that the Dwemer may have survived and sealed themselves into underground chambers where they took a vast amount of supplies etc (which would explain the lack of cogs, machinery etc)
  
• 3- Another option would be the same as both above but much darker. The Dwemer hid, they took everything with them and moved deeper underground. But they sealed their own fates with inbreeding, disease, and eventually mutations. 1 smaller city at least could be found where the survivors can be found. Friendly, intelligent but mutated, sterile and dying? OR cannibalistic, split into classes with the lower class males used as slaves, the lower class females kept like battery hens and bred to produce food. Sick but a good twist! This would not permanently ruin the Dwemer possibilities. These are the ones who ran and hid in 1 area, the entrance to which possibly found within the deepest darkest corner of the ruins.
