Ethos
| Spoiler Warning : This article contains spoilers! |

Ethos, also known as "the key" and "the key to interdimensional fusion", is an artifact retrieved in Dawntrail. It's a key component to open portals to other Shards.
About
The Key is within a goblet like construct, with Ethos being held inside. The goblet like construct made out of Electrope was added by Preservation. They used it to open portals to other worlds for invation, yet not every attempt was fruitful. Robor and Alayla from Oblivion took the key and along with their infant daughter Krile they brought them to the Source[1]. Once Ethos is activated, the symbol of Azem appears on it, indicating that both are connected.
Any portals opened with the key is only visible by those that opened it. None other can pass through it.
Behold—the gift of Ethos. Yours is a journey without end, conceived and guided by principle. Hold fast to what you must, and meet your fate without fear. Go forth. Discover. Unite the stars unto one. Let none bar your path.

Abilities
Together with Azem's crystal, it can open paths to other shards.
History
The key is first used during the Fifth Umbral Calamity, where the Lalafell prayed to the key to safe them. By doing so, it opened a portal to the Ninth, where those surviving the calamity went through and would become the Milalla.
Many years later when the Ninth was facing the Storm Surge and new sources of aether needed to be found to sustain the Endless, Preservation hired two Milalla scientists - Robor and Alayla. Alayla was the current "Speaker" and the keeper of the key. Together they researched interdimensional fusion and studied the key, leading to the creation of an electrope gate in Living Memory which connected to the Source. The gate was built in the Skydeep Cenote in Yak T'el. When they learned that Preservation intended to steal the aether from the source, they stole the key and opened the gate. On the other side, they met Gulool Ja Ja, Ketenramm and Galuf Baldesion. Robor handed the key to Ketenramm, while Alayla handed their daughter to Galuf before they crossed the gate again, sealing it shut. Gulool Ja Ja took the key for safekeeping.
Dawntrail
Twenty years later The Rite of Succession took place, and Wuk Lamat, Koana and Zoraal Ja as well as Bakool Ja Ja were tasked to find the "city of gold". Zoraal Ja was disqualified from the rite, and conspired together with the palace seer Sareel Ja to become ruler. Sareel Ja stole the key from the Dawnservant's vault and they opened the gate[2]. Zoraal Ja made a covenent with Sphene and induced an interdimensional fusion between Everkeep on the ninth and the Yyasulani region on the source. After Zoraal Ja was defeated, Sphene took the key to continue harvesting aether for the Endless in Living Memory.
Before the fight with Queen Eternal, the key reacted to Azem's magic[3]. After her defeat, the key got into the possession of the Warrior of Light.
Etymology
The word comes from the Ancient Greek ἦθος, êthos, for "character", "custom", or "habit".
