Dimensional Timeline Monitor

The Dimensional Timeline Monitor (DTM) is a device used by the Library to monitor and record other dimensions. It is located in the Borges Library in a pocket dimension of Dimension S-2012.

The DTM is powered by amethyst crystals and functions as a listening device for interdimensional space. As a result, it is able to pick up signals from other dimensions. Due to the nature of the DTM, it can only detect dimensions inhabited by advanced civilizations which have begun to emit signals themselves. In most cases, the detection of a new dimensions is often followed by the unexplained collapse of said dimension. One major hypothesis of the Library is that as soon as a civilization hits the required level of technology to emit signals, it lands in a rapid wave of technological progress eventually leading to careless use of transdimensional energy and the collapse of the civilization's home dimension. In addition to detecting other dimensions, the DTM is also able to detect crossover events between dimensions. The Library uses this data to search for other transdimensional organizations and civilizations in the Multiverse. So far, it has been unable to detect an organization of similar size and strength as itself. Most crossover events have been recorded as natural or manmade disasters rather than the purposeful exploration of the multiverse by entities other than the Library.

So far, the DTM has recorded the following information on other dimensions:

* Dimension A-2011: the original home dimension of the Library. Its collapse was confirmed some time after the Arrival of humans in Dimension S-2012.
* Dimension S-2012: also known as the Sacred Dimension, operates as the main operation base for the Library. So far it is the only Dimension where knowledge of transdimensional travel hasn't resulted in the collapse of reality. It has however been hit by several convergence events, most notably the displacement events involving Neo Boreopolis and Orwald.
* Dimension S-2014: one of the first dimensions the Library detected using the DTM. At this point in its history, the Library as an organization was still subservient to the Kingdom of Frozyland. This led to the use of its transdimensional technologies to colonize S-2014, resulting in the establishment of Timbuktu in the 4th century AA (*2014*). However, interference from S-2012 eventually led to the collapse of S-2014, the first recorded instance of a human-caused dimensional collapse.
* Dimension S-2019: After the disaster involving Dimension S-2014, the Library was reformed and colonization candidates were more carefully selected. As a result, Dimension S-2019 was viewed as a more suitable candidate after it came into existence in 880AA (*2019*). In 883AA, an expedition was sent by the Kingdom of Frozyland to establish the Township of Ovis as a colony. However, the Library oversaw the existence of native humans in this dimension, which probably led to the eventual collapse of S-2019 not long after its colonization. Due to the speed of the collapse, the colony and its inhabitants were lost and debates around the library arose once again.
* Dimension S-2020: when this dimension was detected by the DTM, the Library was able to confirm the existence of natives and instead of sending colonization missions, the Library sent a delegation to establish contact with the Pontificate of Neo Boreopolis. As the most advanced civilization in S-2020, the Pontificate became a candidate for the first branch office of the Library in another dimension. Located underneath the Statue of the Son, the Library's HQ in S-2020 served the purpose of researching the origin of the signals which were detected by the DTM, since the technological level of the nations of S-2020 had not yet reached the necessary point to emit signals of their own. However, unbeknownst to the Library, scientists from the Pontificate used the Library's presence to set up their own laboratory to research and weaponize transdimensional energy. This inadvertedly caused the Great Collapse after an incident involving Interdimensional String Energy. Neo Boreopolis was displaced and transported to Dimension S-2012, while individuals were also scattered through the multiverse, most notably to R-2021.
* Dimension R-2021: the Library began picking up signals from R-2021 shortly after the Great Collapse. It was discovered that a handful of Neo Boreopoleans were transported to this dimension and had set up their own civilization, the Pontificate of New Eliyah. Contact has since been established, but interference remains limited to avoid the collapse of yet another dimension.
* Dimension T-2021: similar to R-2021, T-2021 was discovered after the DTM detected a small crossover event from S-2020 to T-2021 moments before the Great Collapse. An expedition was sent and plans were drafted to construct a mobile base of operations in T-2021. It was eventually discovered that Principe Tom from the Free Principality of Tomopolis had been transported to this dimension and had begun setting up a colony. However, the Library eventually lost contact with T-2021 and assumed that this reality has collapsed as well.
* Dimension T-2022: T-2022 has been the latest dimension detected by the Library. Because of the history of interference leading to collapses, the Library strictly opted to stay out of T-2022 and to even refrain from sending expeditions. Instead, it only monitored the signals being emitted by T-2022. However, this reality eventually collapsed in on itself as well as a result of sabotage actions disabling a transdimensional listening device known simply as the Device. Due to the fact the DTM was honed in on T-2022 at the time, the continent of Orwald was displaced and transported to S-2012. Scientists of the Kingdom of Corellia have since been banned from researching transdimensional technologies, unless they do so in the controlled environment of the Library.
