Timeline

This is a general timeline for the events and content of the Deep-Sea Universe. This list is incomplete.
To increase convenience, the timeline has been divided into four different "eras." The unofficial names of the eras correspond to the themes of the events within them.
:Eras:
:* Pre-Gray era: Everything before The Gray Garden.
:* Gray-Blue era: The events of The Gray Garden up until Wadanohara and the Great Blue Sea. This does not include the events that happen during Wadanohara and the Great Blue Sea.
:* Blue-Black era: The events of Wadanohara and the Great Blue Sea up until Obsolete Dream. This does not include the events that happen during Obsolete Dream.
:* Black-Infinity era: Everything during and after Obsolete Dream.
Everything within an era section is not necessarily in chronological order. 
== Pre-Gray Era ==
The Pre-Gray Era is from the start of time up until The Gray Garden. It contains at least thousands of years, since Kcalb has mentioned having been sealed underground for eons prior to the Great War. The Gray Garden 
=== The Sun's Curse ===
Siralos creates Igls Unth and Ivlis. Ivlis later turns into a devil.
=== The Great War ===
The Great War was fought between Etihw and their angels and Kcalb and his demons. Kcalb was locked up by Etihw before the war. He has mentioned being locked up for eons.
* Kcalb and Etihw said they do not remember how many of each other's subjects they had killed. In the same conversation, Etihw mentioned Kcalb has more blood on his hands. 
** Ivlis has said the Gray World was "built on a thousand sacrifices" at the end of The Gray Garden, in reference to the amount of angels and demons that were killed.
* The angels and demons are buried together in The Gray Garden. This might indicate when they were killed.
Etihw repopulated the world through creation after the war ended and reincarnated some of the fallen soldiers from the war. Yosafire’s generation is part of this repopulation. The reincarnations might not have been created at the same time seeing how there are age differences among them, as is shown with the Preserves sisters.
=== Three Divine Beasts ===
The creation of the Three Divine Beasts (Aounabara, Artamos, and Kigisu) is an event that took place during either the Pre-Gray or Gray-Blue era. Artamos has mentioned being around for "thousands of years." This indicates the creation of the Three Divine Beasts took place around 2.000-10.000 years before the start of Wadanohara and the Great Blue Sea.
* Satanick creates Aounabara, Artamos, and Kigisu.
** Chlomaki mentions being born before the Blue Sea existed. This would also place her creation in the Pre-Gray era.
=== Seaside Dispatches 2 ===
Seaside Dispatches 2 takes place before the devil mini-comics, thus taking place in the Pre-Gray era or early in the Gray-Blue Era.
== Gray-Blue Era ==
The Gray-Blue era starts with The Gray Garden and ends where Wadanohara and the Great Blue Sea starts. The duration of this era is unknown. The main indicator of this era is the Devil mini-comic that shows Artamos in his bunny form with Satanick, thus taking place after The Gray Garden but before Wadanohara and the Great Blue Sea.
=== The Gray Garden ===
The events of The Gray Garden take place. This is the start of the Gray-Blue era.
=== ATTACK! Devil-ish Style ===
Satanick, Ivlis, and Siralos pay a visit to the Gray Garden. This takes place before Licorice and Silhouette were born.
=== Buri~ing ===
Buri~ing takes place before Seaside Dispatches 1. It is unknown whether it takes place before or after ATTACK! Devil-ish Style.
=== Seaside Dispatches 1 ===
Since Satanick and Ivlis know each other in Seaside Dispatches 1, this manga takes places after the ATTACK! Devil-ish Style comics, but before most of the other mini-comics. Licorice is conceived and born in this manga.
=== Satanick-Based Mini-Comics ===
Some mini-comics are confirmed to take place within the Gray-Blue era. They take place after The Gray Garden and before Wadanohara and the Great Blue Sea. Some can be put in chronological order. These include:
* Distorted Love
** Ivlis and Satanick know each other. They only meet after The Gray Garden.
* Distorted Love 2
** Sequel to Distorted Love.
* Rainbow
** Sequel to Distorted Love 2. Artamos is still in his bunny form, confirming it takes place before Wadanohara and the Great Blue Sea.
=== Blue Sea Events ===
These events took place either during the Gray-Blue era or the Pre-Gray era.
* Meikai sacrifices himself for the Sea Kingdom, ending the war between Mikotsuhime and Uomihime.
* Wadanohara is born.
* Tarako is the only one younger than 100 years during Wadanohara and the Great Blue Sea, putting their birth in the last hundred years of the Gray-Blue era.
== Blue-Black Era ==
The Blue-Black era starts with Wadanohara and the Great Blue Sea and ends where Obsolete Dream starts. It has been formally confirmed Obsolete Dream takes place after Wadanohara and the Great Blue Sea, as also implied in chapter 7 of Obsolete Dream. 
=== Wadanohara and the Great Blue Sea ===
The events of Wadanohara and the Great Blue Sea take place. This is the start of the Blue-Black era.
== Black-Infinity Era ==
The Black-Infinity era starts with Obsolete Dream and has an undefined end.
=== Obsolete Dream ===
The events of Obsolete Dream take place. This is the start of the Black-Infinity era.
=== Ice Scream ===
The events of Ice Scream take place. Squid is present throughout Ice Scream, and since he arrived at Iceberg Isle at the end of Wadanohara and the Great Blue Sea, Ice Scream therefore takes place after Wadanohara and the Great Blue Sea.
=== Poor Shrimp-based Mini-Comics ===
The Poor Shrimp-based Mini-Comics take place after Wadanohara and the Great Blue Sea when Roc has kidnapped Lobco.
=== Later Events in the Blue Sea ===
Samekichi returns to the Blue Sea (as seen in the Wadanohara and the Great Blue Sea epilogue). Minami is born and some undefined time later adopts his familiars.
