Stone of Gracen

The Stone of Gracen was forged by Ray Lewis in 1892, it has a special power to reverse the aging process (that is why Lewis is still living today). But, only one Gracen Stone was ever found and it is owned by Horden Capoent, who used it to forge Jack Knight's sword (however the powers work even today).

The Beginning of the Story
The Stone of Gracen was forged in the Lewis Mining Facilities on July 13th, 1892. He mixed the genetic formulas of a unicorn and a little bit of dragon blood to form an elixir, that is able to be used to reverse the aging process. But during the Third War of Two Nations, the Lewis Mining Facilities was invaded; causing Ray Lewis to spill his life-lengthening elixir on a stone, the Stone of Gracen.

Destruction
The Stone of Gracen was destroyed in 2014 when Gerald Beck, one of the many who would do anything imaginable to get the Stone, was killed and Jack's sword, which housed the Stone of Gracen was destroyed to prevent further issues.
