As the host of Dance Of The Dead - I am so glad to read your post! I will be certain to convey your kind words to the other people who help organize and run the rp as well!
That said, if you are looking for a Horde faction rp guild, I recommend checking out The Horde Vanguard.
The Horde Vanguard info can be found here: ⫸ The Horde Vanguard - Horde RP Community ⫷ - it is a newer IC RP community that has formed to specifically focus on the Horde Faction within the Moon Guard rp community.
