Thanks to the combined efforts of the official Battleborn forums, all easter eggs related to Borderlands 3 have been found.
In each of Battleborn’s five DLCs a small portal could be found and a noise could be heard coming from each portal. Within that noise was morse code. The process of decoding the message proved harder than most would imagine. Two pieces of audio had to be reversed and all the audio contained background noise that interfered with the decoding process. After weeks of trying to figure this out the message was finally decoded by user WhatsMyNameAgain
CHILDREN OF THE VAULT
WE ARE NOT ON PANDORA ANYMORE
TANNIS IS NOT WHAT SHE SEEMS
DO NOT OPEN THE VAULTS”
Promethea (presumably the same word as Prometea) is a planet where the Atlus corporation first found alien technology. The planet is also stated to have even worse living conditions than Pandora by Atlas propaganda and citizens of Sanctuary. Going to this planet in Borderlands 3 would make sense given its history. It would also give Gearbox a chance to mix things up after having the series take place on Pandora for the majority of four games.
The children of the vault likely refer to Vault Hunters. The “we” in the third line could be Eridians, the creators of the vault. They used to live, at least partly, on Pandora, but disappear sometime after the creation of the vaults. Given their advanced technology, it wouldn’t be a stretch if they still lived somewhere outside of what humans could see.
It is hard to understand why the Eridians would tell Vault Hunters where more Vault are. So far every Vault Hunter has opened or entered every vault they have found. If the Eridians wanted the vaults to stay closed, why would they trust the Vault Hunters with the location of more vaults? Perhaps the planet is not where a Vault is, but where this “we” can communicate with the Vault Hunters who have proved powerful enough to take on the monsters within Vaults.
Finally the most interesting tid-bit is about Tannis. She has always shown to have a greater understanding of Eridians and the Vaults than anyone else. It could be that she has this understanding because she is more than just human. The use of the “what she is” rather than “who she is” leads me to believe this. Tannis could be influenced by aliens related to Vaults or an alien herself.
Tannis has always showed great interest in opening Vaults even to a fault. She had known the location of the various key fragments before the player met her in the first Borderlands. Meaning she was seeking to build the Key and likely use it. Tannis has even seemingly betrayed the Vault hunter in the first game so the Vault could be opened. Commander Steele plainly states that Tannis joined her. Tannis does not refute this and merely states she went along with the plan because it seemed like the Vault hunter would enjoy it. Tannis is not trustworthy and her obsession with Vaults has led her to make questionable decisions. This obsession could put her against anyone who wishes to keep Vaults closed.
So what does this all mean for Borderlands 3? Well the game will either be set on another planet besides Pandora or will take place on multiple planets. Some more advance group is reaching out to “children of the vault”. The scale of the story will go beyond just one Vault and planet level danger. Tannis is more than just an insane bacon hating scientist and will play some antagonistic role in the game.
Gearbox will have a panel at PAX East next weekend on March 12th so be on the look out for more information when the time comes.
