Prison Island (監獄島, Kangokutō) is an area in Xenoblade Chronicles.

Overview[]

Prison Island is a floating island in Eryth Sea, on Bionis' head. Shulk visits the island when Metal Face is about to invade Eryth Sea, along with the Mechon. There are no collectables, Unique Monsters or Heart-to-Hearts. All of the transporters cannot function, since it is a small area. Instead, the party leader has to use the dark transporters, which will take them up to the next floor. There are only three floors visited during the initial visit.

During Chapter 17, this area becomes completely inaccessible and cannot be accessed through skip travel either. However, a brand new area with the same name becomes accessible upon entering the dark transporter in the Bionis' Interior. It is the same Prison Island, but is treated completely separate from the initial Prison Island in the game's coding. As such, it has a different map design, the model is slightly different, and is more explorable. Prison Island lies within Bionis' head, with several changes involving locations and landmarks, enemies, collectables, and Heart-to-Hearts.

Initial Visit[]

Story[]

Shulk with Monado

The Monado is unshackled

It is named Prison Island because in legend, the ancestors of the High Entia imprisoned something here. Soon after departing Colony 6, Shulk has a vision of the terrace, and that the Monado easily slashes through Metal Face's armour. Because of this, he decides to travel here to boost the Monado's power. When he arrives with his party, they head up to the top and find a chained giant; Zanza. Shulk frees the giant, who releases the Monado's power in return, transforming it into the Monado II. Not long afterwards, Metal Face arrives and shoots Zanza and slashes Sorean Antiqua, killing both the giant and the High Entia Emperor. Just as the party is about to defeat Metal Face, Face Nemesis jumps in the way. The armour is damaged, revealing that this Faced Mechon is Fiora, who flies away with Metal Face. Shulk and his friends leave Prison Island, planning to head to Sword Valley and find Fiora.

Weather[]

After the cutscene involving Sorean releasing the seal on Zanza on Prison Island, the weather on Eryth Sea and Prison Island will all transition to a permanent thunderstorm on a random hour of when the next weather change occurs in the game, if the weather is not already thunderstorm. Advancing the time in the game will instantly make the weather change to thunderstorm. However this weather can be changed by travelling in another area like Alcamoth, changing time and weather there (Shooting Stars), then coming back to until the conditions leading to the permanent thunderstorm described above are met again. The permanent thunderstorm weather effect will remain in Eryth Sea and Prison Island until after defeating Metal Face.

Purpose[]

When first mentioned, Prison Island is said to be a floating prison under High Entia Imperial jurisdiction. But it later becomes clear that there is only one prisoner — Zanza in the body of the giant, Arglas. Its only accessible interior room is an entrance path with an opulent staircase and demonic decor. Zanza does not live in this vast interior, but instead was long chained on a high terrace. Furthermore, the High Entia admit that Prison Island was not built by them, but has existed for a very long time.

Chapter 17[]

During Chapter 17, Prison Island is located within the Bionis' head, due to Zanza sinking the island into the head. It serves as the final area in the game that can be used for skip travel. Prison Island is accessed via the dark transporter found inside the Bionis' heart in the Bionis' Interior. Unlike the initial visit, it is now filled with collectables, Heart-to-Hearts, and Unique Monsters.

Story[]

After Bionis awakens, Prison Island sinks into its head. After defeating Lorithia, the party uses the dark transporter to arrive on Prison Island, where they begin chasing after Dickson. Eventually they reach the terrace, where they fight Dickson. Upon Dickson's defeat and subsequent death, the party enters a dark transporter leading to Memory Space in order to confront Zanza.

Changes[]

Prison Island DE Post-MC 2

Prison Island after the Bionis' reawakening

The Eques Skyrays seen flying around Prison Island while it was above Eryth Sea are now replaced with Newgate Laias, the Nebulae that appeared on Prison Island while it was above Eryth Sea have been replaced with stronger types of Nebulae and new enemies have also appeared on all floors. Most of the brand new enemies that have appeared seem to be based off mythological beasts and appear very different than the other enemies found in the game, such as Egels in which seem to resemble gargoyles. Collectables can now be found on Prison Island. Previously the exterior paths experienced the same weather as Eryth Sea, but now the weather on Prison Island is always fair.

The Prison Terrace landmark cannot be used for quick travel, and the dark transporters used by the party before the Bionis' Awakening no longer appear on Prison Island, cutting off the original route between floors GF, 4F, and 6F. Other transporters that had been non-functional during the first visit now work, giving access to the remaining floors 1F, 2F, 3F, and 5F. In addition, an upper walkway on GF can now be reached via the Kitchen on 1F, and two secret rooms on the main level of GF can now be opened.

Purpose[]

Since Prison Island has become more thoroughly explorable, it becomes clear from the layout, the banquet hall and the throne room, that it was probably never meant as a prison at all, but was actually someone's palace. The decor (and the size of the rooms, furniture and flatware) are all of Giant architecture. Since Arglas was a Giant under Zanza's control, and Dickson is a Giant disciple of Zanza, Prison Island may have been a Giant palace or city, appropriated for the use of Zanza's disciples.

Secret Rooms[]

On the final visit to Prison Island, secret rooms with Giants' Treasure Chests can be found, but they are only accessible when the Bone Pillar has been lowered. If the Bone Pillar has already been raised, it can be lowered again by activating the same panel. To get to this panel the Kitchen must be re-entered, requiring the Kitchen Door Key from the hall south of the Arena.

Xenoblade Chronicles 3: Future Redeemed[]

Prison Island (監獄島, Kangokutō) is a location in Xenoblade Chronicles 3: Future Redeemed. It is located on the Black Mountains.

Story[]

When Z used Origin to create Aionios, Prison Island was relocated above the Black Mountains in the Cent-Omnia Region.

After the party's encounter with Alpha at Raguel Lake, Alpha uses Prison Island's defense mechanisms to summon Origin above the region. After making preparations in Colony 9 for the road ahead, the party travels to Prison Island in order to enter Origin.

When the party reaches the top of Prison Island, they spot a dark transporter that will allow them to access The Ark of Origin. Shulk reminisces that it's "just like old times," to which A remarks that in the past, the terrace was where Shulk and his friends had embarked for Ontos's Memory Space from. A then states that recreating the transporter was deliberate on Alpha's part. N then reveals himself to the party, having waited there for them in order to prevent them from reaching Alpha. He states that he will kill Matthew in order to disrupt Alpha's plans, before engaging with the party.

Eventually, Matthew and N clash, resulting in Matthew's Ouroboros Gauntlets releasing a beam of green energy that hits Origin. In response, Origin fires a beam of energy right back at them, which grants the party a glimpse at a memory from Origin showing what truly transpired when N attacked the City and how he truly felt back then. After the memory ends, Matthew scolds N for not understanding what Ghondor truly meant by his actions, which causes N to stand down and allow the party through. However, as Matthew begins to walk toward the transporter, Na'el, possessed by Alpha, appears above everyone, and releases a powerful wave of energy that sends everyone into the Ark.
