{{color|red|Note:}} This zone is likely the first time a player will encounter {{True Sight}} [[Taurus]] and become familiar with [[Fomor Hate]] aggro if they accumulate enough.
:*The zone was originally capped at level 50 and required a group. It is recommended a player be level 60+ if they wish to do it by themselves fairly easily with [[Trust]]s.
:*In addition, you'll want the ability to reapply [[Sneak]] on yourself repeatedly throughout the Mission regardless of your level.

! style="background-color:#9d5353; color: white" | Useful Items to bring:
|- 
| 
*{{ItemIcon|Silent Oil|22}} [[Silent Oil]]
*{{ItemIcon|Reraise Earring|22}} [[:Category:Reraise|Reraise]]
|}
* '''(Optional)''': Speak with [[Justinius]] at (J-6) on the top floor of the [[Tavnazian Safehold]].
** If you receive the {{KI}} [[Monarch Linn Patrol Permit]], this is for the [[Quest]] [[Uninvited Guests]]. Speak to [[Justinius]] again if this occurs.
*Examine the '''Walnut Door''' at (K-7) just up the ramp from [[Justinius]] for a cutscene.
*Travel to (G-4) in [[Misareaux Coast]] and check the '''Iron Gate''' for a cutscene and enter the [[Sacrarium]].
**The [[Misareaux Coast]] [[Home Point]] #1 will bring you very close.
*Once inside, head to the maze section in the southeast of Sacrarium Map 1 to the right.
**The maze changes based on the game day, see the map for the current day's layout. Your goal is to move to connection point B, putting you on southwest section of Sacrarium Map 2.

===Opening the Doors===
*The next goal of the mission is to get past the large door with 2 keyholes at (H-7) on Map 2. There are multiple ways of going about this, depending on your circumstances.
----
'''If Solo''':
*You can ask others in-game if they have done the quest [[A Hard Day's Knight]] to obtain the {{KI}} [[Temple Knight key]].
**If you have obtained this key item from the quest then you can open the doors for everyone and continue onward.

*To complete the quest and finish this mission on your own, you will need to farm the {{ItemIcon|Coral Crest Key|17}} [[Coral Crest Key]] <sup>{{icon|rare}}/{{icon|ex}}</sup> from Fomors on Map 2 and also acquire the {{ItemIcon|Sealion Crest Key|17}} [[Sealion Crest Key]] <sup>{{icon|rare}}/{{icon|ex}}</sup> from the NM [[Keremet]].
** Instead of trading these to the door with two keyholes, instead return to [[Tavnazian Safehold]] and trade them to [[Quelveuiat]] on the middle floor of [[Tavnazian Safehold]], south of Home Point #1 (I-10) across the bridge.
***If you have not started the quest yet then [[Quelveuiat]] will ask you to defeat [[Splinterspine Grukjuk]], which is spawned from the quest at the ??? at (H-10) in [[Lufaise Meadows]].
****After defeating the NM and speaking to [[Quelveuiat]] once more you may then trade them the keys to obtain the {{KI}} [[Temple Knight key]].

'''If in a party of multiple characters''':
*You can skip the quest and farm '''two''' {{icon|rare}}/{{icon|ex}}[[Coral Crest Key]]s from Fomors on Map 2 and {{icon|rare}}/{{icon|ex}}[[Sealion Crest Key]] from the NM [[Keremet]] to do the mission without leaving the zone. 
**Note that the {{ItemIcon|Coral Crest Key|17}} [[Coral Crest Key]] has a {{rdrop}} rare drop rate, so it maytake a number of Fomor.
*See [[Keremet]]'s page for notes on fighting him if doing this at/near level cap.
**There are two hallways leading to the NM. Each lined with six skeletons named Azren Kuba.
***These will all aggro the moment you attack Keremet, but have very low HP. You may defeat them before attacking Keremet.
----
'''After Obtaining the Keys or KI''':
*Proceed to the door at (H-7) map 2. 
**If using the keys, have one of your party members with a {{ItemIcon|Coral Crest Key|17}} [[Coral Crest Key]] trade it to the small keyhole and when a click is heard, the person with the [[Sealion Crest Key]] should trade it to the larger keyhole.
**The {{ItemIcon|Coral Crest Key|17}} [[Coral Crest Key]] will break upon use and you have a very small amount of time to trade the second key after the first has been traded. 
***If you messed up the timing then you will have to farm an extra {{ItemIcon|Coral Crest Key|17}} [[Coral Crest Key]].
*After entering, take a right at the fork in the path, proceeding to the '''Wooden Gate''' at (G-8) for a cutscene.
----
Keremet will only spawn at night (20:00 - 04:00). It will not de-spawn during day hours, but once killed will not respawn until night.

===The Old Professor===
Exit back into the main hallway through the keyhole door at (H-7).
*[[Old Professor Mariselle]] spawns randomly from one of the "???" found on the desks in the six nearby classrooms. There are three classrooms on the north side of the area and three on the south side. Try each desk "???" in these rooms until you pop [[Old Professor Mariselle]], which spawns with two weaker ghosts named [[Mariselle's Pupil]].
**It may be a good idea to clear the Fomor from the room prior to attempting to pop the NM so you can face it and the adds alone.
**Mariselle will periodically warp around the room during the fight.
**This is where being aware of [[Fomor Hate]] reset is useful. Popping the NM will cause you to lose [[Sneak (Status)|Sneak]] and if you happen to have [[Fomor Hate]] and lose [[Sneak (Status)|Sneak]] in a room full of Fomors, you're going to get aggro.
**Only those who are currently on this mission may spawn the professor. Other players will get the message there's nothing in the drawer.
*After it is defeated, everyone on the missions needs to check the '''???''' to receive the {{KI}} [[Reliquiarium key]].


===Wrapping Up===
*Head back to the large door with the 2 keyholes at (H-7).
**The {{KI}} [[Temple Knight key]] will let you slide right through if you're using that method.
**Parties of multiple people will now have to use that second {{ItemIcon|Coral Crest Key|17}} [[Coral Crest Key]] and {{ItemIcon|Sealion Crest Key|17}} [[Sealion Crest Key]] to repeat the process from earlier.
**It is also possible to leave one person behind the locked door, and reopen it using the switch.
*Once past the doors, return to the same '''Wooden Gate''' again for a cutscene to end the mission.
