Commencement

Commencement is the final stage Environment added in the 1.0 Update, and revised in the Anniversary Update. It is located on the moon of Petrichor V.

The will allow its selected monster to spawn, but not prevent the, , or  from spawning.

Description
Commencement is a large domain located above the shattered breach of Petrichor V's moon. It is ostensibly the desolated seat of Mithrix's power.

It is made up of the shattered remains of four individual sections, emblematic of Mithrix and Providence's tools of creation:
 * The area where Pillars of Design are found appears to be a workshop of sorts, with the unfinished remains of a Lunar Chimera Golem. The upper half of one remains suspended by large chains as if abandoned in the midst of construction.
 * The Pillars of Blood are found within a large circular arena, encircled by tall pillars with raised platforms resembling seating.

Raised high above the rest of the grounds by what appears to be a titanic arm is a massive circular area, where Mithrix himself remains.

Releasing the Rescue Ship
Upon entering the main area of the stage, the player will discover a Rescue Ship protected by an unbreakable force field. Their new objective will be to find a way to release the Rescue Ship in order to escape the planet.

Different pillars are scattered around the stage. The player's objective is to activate and charge (i.e. complete the holdout event) 4 of them in order to activate jump pads that will lead to, the final boss. 4-7 pillars will spawn in total and there can't be more than 3 pillars of a given type at once. Each pillar type has its own way of charging:
 * Pillars of Mass take 60 seconds to charge, and have no special properties.
 * Pillars of Design take 30 seconds to charge and release shock waves during the process. These deal no damage, but they push the player away inflict the status, reducing their armor by 20 and movement speed by 50%. The shock waves can be avoided by repeatedly jumping.
 * Pillars of Soul take 30 seconds to charge, but their charging radius will shrink the more they charge. The pillar's charge also rapidly decreases if all players leave the charging zone.
 * Pillars of Blood take 10 seconds to charge, but they absorb the health of the player in the process. The pillar will drain 10% health per second, for a total of 100% over the charging duration.

After completing this event, the game is over. An ending cinematic is played during which the ship can be seen flying away from the moon. Shortly thereafter, a purple void sphere grows from the center of the moon before vanishing in a flash of light, taking the moon with it.

Cauldrons & Lunar Pods
On the left end side of the stage, near where the Pillars of Design spawn, there will be 5 Cauldrons, randomly selected between Common, Uncommon and Legendary. Common Cauldrons are unique to Commencement and will exchange one red item into three of the displayed item. (This area is colloquially referred to by the community as "Soup Island").

On the right side of the stage, near where the Pillars of Soul spawn, there will be 0-5 Lunar Pods that can be attached to walls and in other unusual places.

Shrine of Order
A Shrine of Order will always spawn on a floating rock behind the area where Pillars of Mass spawn (left of the map when starting from the Rescue Ship, see the Overview section).

Logbook Entry
Like the Hidden Realms, Commencement's Logbook Entry is obtained through picking up an Environment Log. Said Environment Log is located within the central hole underneath the boss's arena. It will disappear 5 minutes after entering the level.

Trivia

 * A 'commencement' is a beginning or 'start' of something, an apt name given the nature of Mithrix and his brother's involvement with creation.


 * The implosion of the Moon in the ending cinematic is reminiscent of the death implosion of a, albeit on a planetary-sized scale. It could be assumed that the Moon was not actually destroyed, but rather 'detained' in the same way that something caught within the Void Reaver's implosion is described as.


 * A glass frog can be found during the escape sequence. It can be found by returning to the Teleporter ring at the start of the level, but only after defeating Mithrix.
 * This Easter egg was requested on the official Discord. The log refers to "glass frogs", implying that the frog could be more than an Easter egg.


 * The Pillars in this stage are all based on the 4 elements of the universe Mithrix found. What they are, how they function, and how they look are all taken from the Bulwark's Ambry log.
 * "...Round, with no features. No orientation. It is mass. Almost everything here is mass. Mass is boring, but required." The Pillar of Mass is the blandest in design, and has no effects. Featureless and boring.
 * "...Features, angles, and intent. Look at the planarity of the surfaces. This is design. I love design." The Pillar of Design has a clear design unlike most of the other pillars, and has a distinct feature - its twisted design.
 * "...a volatile one - a lifeline. Blood. Sharp, yet radiant. Blood is heat. This is my blood, but there is plenty of blood in this universe." The Pillar of Blood is literally a pillar made of blood. Perhaps made of Mithrix's blood given the log, and how desolate the moon seems to be.
 * Prior to the map's redesign, a Pillar of Blood could be found near the Cauldrons as decoration.
 * "Now be gentle. Look closely here. Do you see it? Almost invisible, a thin film. Frail. It’s not in this reality, but an adjacent one. I’ve heard you discuss this - something you innately understood. What you describe as soul. Don’t you love soul?" The Pillar of Soul is nearly invisible, and it being the frailest of the elements, it requires the most amount of attention when charging.
