Xarcabard, Land of Truths

Details
You must go to Castle Zvahl in Xarcabard. The President himself will brief you in his office.

Walkthrough
1. Start the Mission by talking with one of the Bastok Mission Starters.
2. Go to the President;s Office and talk with Karst
3. Head to Castle Zvahl Keep and into the Throne Room. Select The Shadow Lord Battle BCNM to go into the uncapped BCNM fight.

Castle Zvahl is located in Xarbacard. Go west from the vars crystal and you'll reach there in a very short time. You may aggro some Evil Eye or Demons along the way, but do not worry, just run into the entrance.

After entering Zvahl Bailey, you have to work your way to the west in the first map. The monsters over there are not strong, so go ahead and fight along the way if aggroed (you can walk behind Evil Eyes (if high enough level, if not, sneak) and Demons and not get caught). When you see the first crossroad, don't go through the middle (dead end). Go around the left or the right road.

From the 2nd map, cast invisi and go through the area to the west again (look at the map and see how). If you reach the "Quadav Region", cast sneak instead. After this map, you will reach Zvahl Keep.

At this point, just keep fighting when you see any enemies. In the first map, find your way to the top of the map. In the 2nd map, find your way to the west exit of the map.

You should have reached a series of teleport devices. Be careful of the demons, but you should be able to get behind them and not get detected. After the last teleport, just run to the west exit of the map. Don't worry about demons/eyes that get aggroed and head to the zone line. Open the door and exit.

You have reached the the final area. Rest your HP and MP to the max, and gather in front of the door. When you enter, you'll see an event and the fight begins.

4. After defeating both forms of the Shadow Lord, a long cut-scene plays out, which provides the Shadow Fragment key item.

There are 2 forms of Shadow Lord, and the first stage is the most dangerous. When you enter the room, do not fight Shadow Lord first. Cast your prefight spells (protect/shell/etc) and eat your power up food. At the beginning of the fight, have a main fighter attract all the attention, with that fighter use his 2 hour skill. All the mages go up the stairs and start curing (with the main focus on the main taunter).

When Shadow Lord enters its invincible mode (you'll see the fighters doing only 0 damage), the mages should start firing damage spells (preferably ancient spells). If out of MP, use yagudo drinks, or even use the black mage 2 hour skill to continue bombing. When the invincible mode is over, the magic attacker should rest MP. The rest of the fight should not be a problem.

After the first form of Shadow Lord is beaten, you'll see an event. After the event, fighters use the silent oil, and the mages can use silent oil or sneak. After that, rest the HP and MP. Be careful if sneak is about to be wear out!

When everybody is in full health and ready to fight, everybody come in close to fight the 2nd form of shadow lord!!

In this form, all Shadow Lord does is a wide area attack. All mages should simply use their curega spells. All fighters should activate their 2 hour skill and use their strongest weapon skill whenever they can (no renkei). Shadow Lord should be killed rather easily in this mode.

5. Return to Bastok and report
