Sunless Sea

All these complicated endings are all well and good but I got it under 3 minutes.

Its pretty easy, once you have a Scion and at least 1000 echoes.

Start a new game and get the pupil or salvager legacy, so you start the game with at least 1000 echoes.

At the start of the game, choose a Path Wreathed In Shadows

In London, go to Your Lodgings and then buy a Townhouse.

Retire.

Achievement Get!

A few seconds east of Fallen London you will find Badstevener's Abyss and if you dive in that zone, you will find one of the 15 abysses.

You can spot abyss sites in the chart (map), they are shown as black circles, you cant miss them.

The abyss rites are randomly generated and if you find one, succeeding in a rite inside the Abyss will give you the chance of modifying some of your stat, do so and you will also unlock this achievement.

There are more abysses out there where you can unlock this achievement at, but this one is the closest to the starting point.

You can find the same rite in different abysses.

See the guide The Lady's Parlour to see which order you need to perform the rites to unlock the Lady achievement.

So you might want to reload or at least forsake the ritual after you are done if its not the Scripture rite.

Cheers.

Wrack is an underwater settlement located a little south and southeast of the Salt Lions.

Anthe is an underwater settlement located south of the port of Mount Palmerston.

The undercrow settlement can be found in a quick zub dive underneath The Ragged Crow landmark.

Its usually to the north of the map, but since the map tiles can be shuffled around from game to game, it might shift location.

Nook can be found southwest of Nuncio.

The underwater settlement of Dahut is between the town of Godfall and Polythreme.

Scrimshander can be found underwater northeast of the Sea of Lilies.

You can find the underwater settlement of Rosewater east of the town of Visage.

This will require some time.

You will need to enter Dahut for this one and the requirements to enter are Recent News from London and Something Awaits you at Port.

To get Recent News, go into where you are Lodging in London and read the newspaper.

To get Something awaits, its a random thing you can get while travelling the zee, its just a matter of time and luck.

Once you can enter Dahut, do activities to increase your stay until its above 4.

Once its above 4, you can go to the Spring Rites, Midsummer Festival or Liturgy of Souls, each of those gives you one song.

The availability of those events depend on your clarity and enthrallment level.

Each time you get a song, you will need to go back to London to get recent news and sail enough to make awaits at port.

Spring Rites

To unlock this option you need: Clarity ≤ 3 & Length of stay ≥ 4 and ≤ 9

You need to pass: Linger-> Enthralment challenge (17 for 100%)

This will give you, Drownie Love Song

Midsummer Festival

To unlock this option you need: Length of stay ≥ 4 and ≤ 9 & Enthralment ≥ 15

You need to pass: Linger → Clarity challenge (13 for 100%)

This will give you, Drownie Song in Counterpoint

Liturgy of Souls (Using a needle or a lucky unread log is the easier way to get this one, once you have less than 3 enthrallment, you can endure to keep it down)

To unlock this option you need: Enthrallment ≤ 3 & Length of stay ≥ 4 and ≤ 9

You need to pass: Keep awake, awake! → Clarity challenge (25 for 100%)

This will give you, Drownie Hymn

You can also bring Unread Logs and/or Needles of Fortas for more options.

Good luck! Remember the Needles, its the key!

I can confirm this achievement is working as fix as of 2020.

The bomb is a super rare random encounter you find while exploring the underzee.

You know, those blue spirit sprites you see everywhere and then turn into ships/enemies/weird stuff? those are the random encounters.

It took me like 6 hours exploring the underzee with my zubmarine until I finally found one.

This is what it looks like:

BUT get this... in order to get this achievement, you must successfully pass a Chance check at 50%.

So, even if you find one (maybe I was unlucky and its more common in other people's game) even if you find one, you have 50% of NOT getting the achievement.

If you fail, I strongly suggest you reload your last autosave if you can and hope you find it at the same spot again.

My luck about not finding the bomb gave me enough luck to pass the check on my first try, so Im not sure if the above would work.

I found my bomb a little bit east of Fallen London out of all places.

Anyway, hope this info helps and I wish you best of luck!
