Once you receive the note, simply speak to Snak gra-Bura at the Chestnut Handy Stables outside Imperial City. She will give you a free set of either Elven Horse Armor or Steel Horse Armor. Subsequent horse armor may be purchased for 500 .
If you do not own a horse before going to Snak gra-Bura then she will give you a free one with armor. It is not very good, however. It is named "Old Nag."
Occasionally, you will come across notes within certain caves (it is unknown as to whether or not there are specific caves that have these, or if it is purely random) that mention traveling to the Chestnut Handy Stables about the armor.
Upon installation of the mod and entrance into the game:
- I've discovered a notice from Snak gra-Bura of the Chestnut Handy stables. She is offering to outfit a horse with armor at no charge to anyone who presents her with a note like the one that I've found. I should bring my horse to her and take advantage of this offer.
Upon speaking to Snak gra-Bura:
- Snak gra-Bura armored my horse for free. From now on, she will outfit any legally owned horse that I bring to her with Steel or Elven armor for 500 gold.
