Start the quest by speaking to Advisor Ghrim on the second floor of Miscellania Castle.

He will tell you to talk to Prince Brand and Princess Astrid. Talk to one of these and a cut-scene will follow that tells you the King is bored and causing a bit of trouble, war is likely to break out between Miscellania and Etceteria. One of the solutions Prince Brand thinks is a marriage between King Vargas and Queen Sigrid. Well it is up to you to solve the problem.

 

Now head for Etceteria and talk to Queen Sigrid. She will tell you her citizens have reported items stolen. Go outside and talk to 3 Citizens, they will tell you Miscellanian soldiers are to blame for the theft of the items. Report this to the Queen and she will order you to speak to King Vargas, after all you are the Regent and should solve this.

Speak with King Vargas and he will tell you about missing items in Miscellania and orders you to talk to Leif, Magnus and Frodi. Leif is cutting the maples, Frodi is the fisherman at the docks and Magnus is the one mining coal at the north side of Miscellania.

 

After you have done this speak first with Queen Sigrid and then with King Vargas. King Vargas tells you to speak to Advisor Ghrim again, as he is probably the one who knows about strange elements stealing things. Do so and he will tell you the one most likely to know about strange arrivals is the Sailor on the docks. Head there and he will tell you about the dungeons.

Dungeon is not the right word for it as the dungeons are being excavated to house new arrivals. A whole new village, complete with pub and general store.

Now go back to King Vargas, speak with him and ask permission to enter the dungeon. He will give you a Scroll that will allow you to enter.

 

Location of the dungeon is at the south end of the castle: take the ladder down, a guard will stop you but you have your scroll with you so you can enter.

Talk to the store owner and he will tell you about a cave filled with water and monsters lurking about. But the dwarves would know more about this. Go the the most northern house and talk to one of the Dwarves.

Any of them will tell you to talk to Donal in the pub.

Go through the whole conversation, Donal will give you a mining prop that will help to safeguard you from falling rocks squeezing through a crevice. Head to the north western side of the cave, use the prop on the crevice and you enter a room. In this room you will find a few crates, an engine and a lift manual. Read the manual and you will need the following items from the crates: 3 pulley beams, 3 beams, 1 engine, 1 rope and 1 manual.

 

First use a pulley beam on the Scaffold. Use beam with pulley beam in your inventory to get a 'long pulley beam', use beam with this to get a Longer Pulley Beam, use this with Scaffold the top beam will be in place. Now use the 3rd pulley beam on the scaffold again to get the 2nd cross member in place. Next attach a rope onto the pulleys, then use your last beam on the platform to repair it. Finally use engine with engine platform and finally use your 5 coals with the engine. You now have a working lift.

If you forgot to bring coal the rocks next to the lift can be mined.

Take 1 rope from the crate, use the lift and pick up the plank lying there. Then enter the tunnel.

Head east until your path is blocked by water: Use your rope on the left hand side of the rock above. You now have a rope swing.

Walk further east until you reach a fire: search it and you will have a burnt diary in your inventory.

Walk along and again you will reach water. Use your plank on the rocks to traverse this obstacle. If you do not use the plank you can cross but you will get hit up to 16 per try.

Search the fire at the end to find more diary pages.

Follow the path and find another fire, search this and again diary pages are added. Now head on and watch the steam vents.

They can hit for 9. Keep following the path and search every fire. At the end of the cave you should see another crevice to crawl through.

Read the diary, now with 5 pages added, and you can crawl through. You enter a room and a cut-scene follows with 5 youths of Rellekka trying to become adults. After this head down the tunnel and prepare for the final battle. On your way there you will find different stages of the level 149 Giant Sea Snake you need to fight. Run past them until you reach a crevice, prepare and crawl through. Killing the Giant Sea Snake should be not very difficult but he will poison you and these poison hits start at 9, so use your anti poison potion. The fighting style used by the snake is a combination of Magic and Melee.

When killed, the Giant Sea Snake will drop a Heavy Box, containing all the stolen items. Head back out through the crevice and a guard will drop a rope, or tele to Camelot and run back (or use lyre teleport) to Queen Sigrid to report. She will praise you and add the resources of Etceteria to those of Miscellania as an extension of the reward for Throne of Miscellania quest. She will also give you a letter for King Vargas. Head over there and hand him the letter, go through the conversation and: Quest complete!!
