Yuf

Yuffius Yuffii is an abnormal species found predominantly in the ingame-help-section region of the Fox Coalition server. The species is believed to have quantum-particle-like behaviour, making many details of the species uncertain, such as number in the wild, active periods during the day and whereabouts. Its exact appearance is also only presumed, and has, in rare cases, been known to change. As a result, the appearance of the related species Yuffius Yuubaris is frequently used to represent Yuffii, although this can be misleading as the two species are very different. There is only one confirmed individual of the species, named Yuf. It is unclear if sightings of "Yuf" in different servers are different individuals, or the same individual superimposed in different servers by quantum uncertainty in its position. It is sometimes referred to as "Schrödinger's Yuf" due to its quantum mechanical nature. 
=== Etymology ===
The term Yuf, both of the species and the individual, is derrived from the individual itself. It is believed the name originates from a random string of letters, formed during its creation prior to the stabilisation of its wavefunction, although no evidence has been found on the time this name was adopted. Yuf is also known to go by the name "Phoric", suggesting that there may be multiple Yuffii, who are similar enough to be mistaken for each other. All Yuffii may be in a state of quantum entanglement, hence exhibit identical properties, even if they are distinct individuals.
=== Origins ===
It is most commonly accepted that Yuffii originate from Britain, however there is some evidence suggesting that they infact originated in Japan. Two possible explanations may explain this: the first is that there are (at least) 2 individuals, one from Britain and one from Japan, which are quantum entangled; the second is that due to the inherent uncertainty in the position of Yuf, it may not have a well-defined point of origin, and its wavefunction may have had significant probability density in both countries to begin with.
First being sighted in the Fox Coalition server in the late v4 era, Yuf made its home in the Lecuture Hall territories of the server, however after the destruction of its habitat in the mid-v9, it resettled in ingame-help-section.
Unlike most beings in the Fox Coalition server, Yuf does not belong to a specific Azur Lane Guild. While the lack of such a faction is rare on the server, its extensive knowledge of the Azur Lane lifestyle implies it does indeed know of it. Differences in the Azur Lane described by Yuf with current knowledge implies it's familiarity with Azur originates from Japan.
=== Behavior ===
Yuffii are known to be extremely territorial, rarely venturing from their home territory. They are known to deter intruders to their territory by threatening them in wikispeak. Whilst wikispeak is known to be very informative, it typically has the side effect of making others leave the ingame-help-section region after sufficient use. Some people have been known to take advantage of this behaviour to obtain knowledge through the wikispeak, although the Yuffii don't seem to mind this. 
The territory of a Yuffii is usually cleared marked by so called "pins" - packets of recorded wikispeak found only in the ingame-help-section region. No evidence of any pins outside of this region has ever been found.
Yuffii are occasionally known to leave their home territory, most commonly migrating south, stopping at the world-of-warships region for water, and the hololive-nijisanji region. In the case of the latter, this is believed to be a result of their Japanese origins, and they are known to understand weebspeak - a language commonly found in the region. Sightings to the north in guild-chat and surrounding regions are also known, but for unknown reasons these have become much less common after the destruction of the Lecture Hall environment.

Is very territorial (#ingame-help-section). Should approach with caution.

Once asked everyone what should I name the new emoji that came from Yuf. Ignored everyone else and just went with ":Yuf:".
