Otherworlds

About
Otherworlds are parallel realms that exist beyond the existence of The Continent. In the wide and infinite array of dimensions that exists in the entire plane of existence, there are many worlds separated from each other. From the perspective of Ludo-Rathowm's world, there are two different types of worlds: Alternate Worlds, parallel dimensions that exist within the larger universe of Ludo-Rathowm's sphere, and External Worlds, outward realms that exist completely independently and distinctly separated from the influence of the Gods of the continent. The Alternate Worlds are also separated but more closely connected from each other as they were formed by the larger beings of the universe, such as the Gods Realm or the Devil Realm. These dimensions may also be much smaller in space, typically created by much weaker beings like the Anise Wonder Maze created by Anise Sawatari. External Worlds have no connection with Ludo-Rathowm and the Gods and were instead formed through other unknown means. The difference between the two may not be as clear at first so as explained by Miracle Tou; Alternate Worlds are like different rooms within a large house that is the universe governed by the Gods, while External Worlds are other independent and disconnected houses. For the majority of the beings in the continent, these "hidden rooms" are inaccessible and usually only higher beings are able to move freely between each.

Gateways to Otherworlds are known as "Gates". The's a mysterious phenomenon in which a Gate randomly appears in dungeons or some other unusual area, often bringing lifeforms from other universes. These connections are temporary however and they tend to fade on their own after some time. There are some extremely rare Gates that are firmly placed, such as at the bottom of the Ragnard Dungeon connecting to Hell or the Ancient Ruins housing a secret passage to the Gods Realm, but these were artificially crafted by the Gods and only lead to Alternate Dimensions. Some of the strange living beings that have appeared from Gates to External Worlds have settled in the continent, continue to breed and expanding their numbers to the point that they become accepted as another race. Humans tend to classify these as Monsters though, as they're visually indistinguishable to them (especially if they're non-sentient). Over the course of history, many types of creatures have been pulled from External Worlds and they tend to be wildly different and absurd in shape and structure to the local lifeforms, like Poly Monsters.

There is an inconceivably large number of Otherworld in the vast plane that conforms the entirety of existence, but there are a handful of beings in the continent that are capable of accessing some of these Otheworlds. The first and most notable is the Demon King, who, granted immense magical power by the Supreme Gods, is able to use a magic called "Gate Connect" to open Gates to Otherworlds as they desire. The other and perhaps more impressive example is Miracle Tou, a Lv3 mage from the Tou Family gifted with an extraordinary talent that enabled her to study, comprehend and utilise the "Gate Connect" magic; effectively granting her the nearly mythical ability to travel through otheworlds. Unfortunately, this form of magic is extremely complex and an extensive amount of information is required in order for her to be able to open a Gate to an Otherworlds. Regardless, through her research she has been able to discover a fair number of worlds and opening a Gate to these takes her no time at all, as she has been extensively studying them. The power to use Gate Connect is considered catastrophically dangerous, since Otherworlds may prove extremely dangerous. Someone may invite an invader that is far beyond their capabilities or gain access to elements that would prove immensely beneficial to them, and in the wrong hands, it could very easily change the continent forever. In fear of potentially destroying the balance of the world, Miracle decided to keep her discoveries secret and approaches the Otherworlds with extreme caution.

Beyond the usual of Magic, it is also possible to access Otherworlds with technological advancements, though the construction of machinery that enables inter-dimensional travel is of such high-level that no-one in the continent has achieved such a task. Races that have crafted this kind of technology are far more technologically advanced, such as the Horus or the Kaiju.

There's also a quartet of mysterious beings called "Parasitic Spirits" that continuosly move through many dimensions and are completely unkillable. They can be defeated in battle, but they will instead simply disappear; only to show up in some other location. They're not violent and are usually hiding in hidden locations but they will engage in battle if provoked. Not much is known about their origin but they are incredibly powerful creatures. They often appear in several Alicesoft games from different setting but the most commonly seen is Gunagan.

Dimension 3E2/"Steel Horror" (unofficial name)

It's a very different world to The Continent that resembles modern real-life Japan a lot, but not much is known about it. Weapons of Mass Destruction have been developed and it seems to be in a state of war. Miracle stated that the technology of this world is capable of eradicating all life from The Continent. It is revealed in Rance X that this is the world Miki and Kentarou came from.

Dimension 3FB
Another dimension that resembles a lot to real-life world, with human civilization a lot more technologically advanced to the one from The Continent. Seems to be pretty similar to 3E2.

Dimension between Space and Time
