Welcome once again my friends to the lore that never ends, we're so glad you could attend, come inside, come inside Know Your Lore.
In the past two weeks we've talked about the formation of the Old Horde on Draenor, and the resulting rise of the Alliance of Lordaeron to oppose them. Unfortunately we were forced to give the actual events of the wars slightly short shrift in the interest of being done someday. So this week, we cover the First War. (Note: there are spoilers for the original Warcraft game and several books and comic books contained in this post. Be warned if you continue to read it.)
When last we discussed the Old Horde, we mentioned that Gul'dan and his Shadow Council were feeling the strain after having been abandoned on a slowly dying world by Kil'jaeden after having apparently slain the draenei. As the demonic corruption slowly poisoned the land and turned the orcs (even orcs who hadn't partaken of the Blood of Mannoroth) a livid green color, two events occurred to forever change the fate of two worlds. The first was seemingly small: a plague known as the Blood Pox started spreading, forcing the establishment of a quarantine zone in Nagrand in the lands formerly held by the Frostwolf Clan. That clan, however, was no longer able to hold those lands due to the second and more immediately portentous event. Gul'dan was contacted by Medivh, the Guardian of Tirisfal and host to the essence of Sargeras himself, and offered to the dark orc warlock the one thing he truly craved.
