Sunless Sea: Zubmariner Edition

The mysterious Lady Black can only be met with the use of a Zubmarine and entering a series of abysses in a specific order.

The Unterzee contains 15 abysses which will appear as circles on your map. Each will randomly be classified with one of four abyss "types" and accompanied by a rite which must be performed as well. What you will need to do is dive into an abyss to reveal which type it belongs to (press X to bring up your journal to perform the action). If it isn't the correct one you need, simply move on to the next. When you find the correct type, "dive deeper" for a skill check at the risk of hull damage then perform the rite. If done correctly, your Abyssal Rites: Approaching Her Ladyship quality will gradually raise.

You will only need to do this four times and in the following order:

1. Abyss of Scriptures; Ritual of Greeting
2. Abyss of Pyres; Ritual of Hearths
3. Abyss of Pomegranates; Ritual of Feasting
4. Abyss of Graves; Ritual of Solace

If done correctly, the Lady will appear and the achievement will unlock. Further, accepting her offer of *cough* "companionship" will end your current captain's journey, but provide a permanent 10 pages boost to all your future adventurers.
