K3

K3 is a neutral goblin base camp located on the southern base of Storm Peaks on the continent of Northrend. The goblins are out to loot the titan machines in the peaks but are having problems with the local wildlife.

K3 is also the location for "Honest" Max - an NPC who will give away a free flying mount, to players that are level 77 and have not purchased Cold Weather Flying:
 * Loaned Gryphon Reins
 * Loaned Wind Rider Reins

Flight path connections

 * Ebon Watch, Zul'Drak
 * Dalaran
 * Brann's Base-Camp
 * Frosthold
 * Camp Tunka'lo
 * Grom'arsh Crash-Site

Inspiration
K3 may be inspired by the mountains in Karakoram mountain which includes mountains originally named K1 to K5. K2 is the second-highest mountain on Earth after Mount Everest.

Also a possible reference to "K-3" a mining planet in the movie "Serenity" created by Joss Whedon.

Many of the goblin defenses are reminiscent of the game Team Fortress 2 by Valve. These include sentry guns, demolition bombs, sappers (although in this case they are people and not devices), and teleporters.
