The undead underground
Many of the undead had started to move. Some to forgotten lands, some to highly populated places and some into large lands located under ground. As decades passed the undergrounds had formed because of the work of the undead, as the undead also formed in order to suit the underground. Mentally and physically they had adapted to their surroundings. Some better then others and some more uniquely then others.

A truly unique kind
Some of the undead had become... mindless. Wondering the underground without goals and without a single ambition or thought passing through their minds. And some had developed entire civilizations. Fully functioning in all aspects and many with some things you couldn't even imagine. Some of the undead had also become horrible monsters, well... some became that way... and some were made that way. There were others too. Ones that no one knew anything about. Ones that had no one alike. The ones named the unique kind. These ones had no names by nature, and because of that they were given to them by the others. They might have used to be ordinary but had become something completely different in order to best adapt to their new home. Not many but some had lost their bodies completely replacing them with mist that resembled complete darkness. Not many but some had grown wings made of unidentifiable material resembling bone. Not many but some had grown horns used for intimidation and for storage of power that is like lifeforce to them. Not many but some had ended up combining all of these together into one. Whilst there were other adaptations too they were not as notable as these nor are they as useful.

A future to await
The past is something unknown to us. The present is being written as we speak. The future is something we can not predict.
