This is the main entrance to Karazhan. On the right is some useless spider waste of time shit. If you clear through it, there is an optional boss, and stairs that lead to the third tier, into the slut hallway with another optional boss. On the left is the http://www.wowhead.com/npc=15550/attumen-the-huntsman. Attumen is optional, but he does drop http://www.wowhead.com/item=30480/fiery-warhorses-reins Procceding past Attumen, a blacksmith becomes available to you, and you proceed up the stairs.
There is some trash here, and an optional boss on the right side of the Scullery. Past the door leads to (http://www.wowhead.com/npc=15687/moroes). If you enter the doorway, or get too close to it, you will agro mobs and sometimes even Moroes himself. Have a caster LoS pull the mobs.
Moroes is in the purple. Past Moroes on the right is the ballroom. After you clear there, at the bottom is a stairway right to the entrance, so if you wipe you can just go through there. I strongly recommend clearing the ballroom asap in case you wipe, you don't have to go all the way back, and on a private server, unless you have premade guild, you will wipe at some point.
From the ballroom stairs, you'll wind up in at the stairs that are about in the middle of this map. If you took the right path (which is really the wrong path) then you'll be at the slut hallway at the top. The slut hallway and (http://www.wowhead.com/npc=16457) are optional. The red boss in the map is the Opera Event (http://www.wowhead.com/npc=16812).
