The Blood Pact is a alliance between most of the Horde's RP guilds on Scarshield legion.
Why do we need this alliance? Allow me to explain by quoting:
"The idea by forming an alliance/coalition/pact/whatever you want to call it between the RP Guilds is simple.
Community.
Roleplayers tend to be social creatures who prefer to deal with those of their own ilk, but if we all huddle together in our own Guilds we will diminish and be pushed into the background by Leet Kiddies and Those Guilds drunk on Purple fever.
By associating with each other we can organise cross-guild plots; get our members to mingle and socialise with a broader spectrum of personalities; increase our pool of talented craftsmen our Guilds have access to; and of course run raids bigger than any one Guild can run on its' own.
In essence we can make roleplaying more interesting for our members and Roleplaying Guilds more attractive than the smattering of End Game Guilds which populate this server."
The current guilds in the Pact are:
The Ashen Order
The Warsong Blades
The Greywolf Tribe
The Heritage of Zandalar
The Extreme Angling Club
