"You said something about rebuilding correct? I can forge weapons and re-create blueprints to buildings and even forge a building of myself. The facility I own now took me two months to make on my own, and its size would have took more then eighteen ponies to build it in two years."
"We will discuss that when we get back." Darky said to him as he started to walk away "Or you can come with us and discuss as we go to where we are going."
"So, what happened to the princesses? Did they die from disease? Old age?" BladeRunner curious as to how these immortals had died in the first place.
"They..." Darky started saying, but you clearly see it was hard for him "died from an ancient plague..." he said remembering the death of Luna.
'I am sorry for your loss," BladeRunner said remorsefully, "I am sure there is a way to bring them back."
"ugh...whatever...you clearly don't care." she stopped jumpin and put her hoof down and used her magic to track down Darky and when she did she jumped on his back. "DARKY!"
"well...it's just that the special thing about my family is that we can go WEEKS without feeling tired after using magic for 10 hours straight!"
