Shadowhorn was a unicorn mare, living in Stable 29 under Fetlock.
After the War
Stable 29 was not provided with an Overmare or Stallion, instead it was run by a Crusader Maneframe, a fact only known to Shadowhorn herself. Shadowhorn possessed the knowledge of how to shut down the Maneframe, should it become dangerous and start killing the residents, Shadowhorn however was not able to use this knowledge in time and was killed by the maneframe.
Littlepip discovers the truth about Shadowhorn's demise from a pre-recorded message she made, in the event she should be killed before shutting the maneframe down.
