The medallion of life
While carrying the medallion a retired horse becomes un-retired and is allowed to enter shows, breed etc.

Notes:
The medallion must be transferred to a horse (on your home page, click on the image and then transfer it to the desired horse)
The medallion works only for the horse carrying it.
The horse can NOT have 2 medallions at the same time.
In order for you to give medallions to more of your horses, you have to transfer them after buying each of them.
Otherwise buying a second medallion will extend the life of the one in your possession.
