Blackrock Camp

The Blackrock Camp, also known as the Blackrock clan village or the Orc Village, was a Blackrock clan settlement in Alterac Mountains in Lordaeron.

It was initially seen in "Blackrock and Roll" as a small village led by the Blademaster of the Blackrock Clan, where he sacrificed villagers from Strahnbrad to his demonic masters at a nearby pit.

Later, in "Blackrock & Roll, Too!," Arthas Menethil and Kel'Thuzad return to the village, this time finding it a massive series of orc towns in a snowy region. The orcs here were defending a Demon Gate.

It was presumably wiped from existence by the Scourge, as it is never mentioned again.

Location
It was south of Strahnbrad, east of Alterac, and west of Durnholde Keep and the river that bisects the Hillsbrad Foothills. While no evidence of this expansive village exists in World of Warcraft, an estimate would put it somewhere around Corrahn's Dagger, Tarren Mill, the Uplands, the Horde entrance to Alterac Valley, or the mountains in that general vicinity.

Trivia

 * Arthas: Rise of the Lich King skips mention of the first engagement with the Blackrock orcs, and while it acknowledges the orc encampment and their Demon Gate during the second engagement, it does not describe the location.
 * The locations of Blackrock and Roll and Blackrock & Roll, Too! on the map weren't on the same spot. The first mission' cross was between the mountains and the camp. The second mission's cross was at the mountains indicating that the two battles didn't occur in the same place.
 * An orc village close to the presumed location of the Blackrock Camp is mentioned in the Alliance Player's Guide.
