Similarities to Earth-Standards #
There are a number of similarities between measurement standards used by Poseans and those typically used by us humans on Earth. Thus should any form of measurement, for which there is a comparable existent measurement system on Earth, show up at any point in the comic, or on this wiki, it can be logically assumed to be similar in nature without further explanation (unless otherwise stated).
This could possibly have an in-universe explanation as it is known that the first wave of Poseans were souls reborn and thus possessed past memories, which would explain why they had innate concepts of the words for the cardinal directions. Thus it could be assumed that they drew upon similar innate concepts for other systems of measurement.
Time Differences #
Posean clocks appear to operate on cycles of 16 hours, and assuming the clocks operate as they do on earth (completing a revolution for the first and second halves of any given day), then the length of a Posean day can be assumed to be 32 hours long.
Based on information provided by a Posean calendar, a Posean week is still 7 days long and a month is 30 days long. The number of months to a year has yet to have been mentioned within the comic, however the artist (Trig) has gone on record as saying that there are exactly 16 months to a Posean year; bearing similarities to the human fascination with the number 12. As each month is exactly 30 days long and there are 16 of them, that means that a Posean year is 480 days.
With a bit of math we can also learn that the time skip between the start of the comic and the time period that the Dreamer arc takes place in is comparable to 1999 Earth years.
Geography #
Posea is comprised of two semi-connected continents, D.A.R.T. to the north and Delsur to the south, surrounded by mostly ocean and a few islands all of which being contained within a walled perimeter, which can be visibly seen on this page and confirmed on this one. This Ellipse is approximately 922.9 kilometers (km) in diameter east to west & 903.5km north to south, meaning the perimeter is ~2868km in circumference, and the total area contained within is ~654,897 square km. Only about 1/4th of the total area is made up of land, thus the livable area of Posea is ~163,724 square km, which is somewhere in between Uruguay and Suriname (if you’re looking for a real world comparison) and is about 0.11% of Earth’s total landmass. This also means that the total water area of Posea is ~491,172 square km, which is about 0.13% of Earth’s water mass.
Astute observers might also have noticed that the map listed above claims that the area beyond the perimeter wall is “Outer Space” going as far as to include depictions of a moon and stars to align it with what we might associate typically with Outer Space. This view is currently seen the most here. However it is not confirmed if what lies beyond the boundary is just the void of space, as on this page a crack can be seen in the boundary from which a bright light shines through, which destroys the illusion of there being nothing beyond.
Politics #
At the time of the Dreamers Saga, the nation of Delsur (capital Hope) is at war with some faction referred to as “the DART”, who’s symbol is an arrow. This conflict has caused numerous problems for the region including an Orphan-crisis and a Famine. The Hope government appears to be attempting to combat these two issues via a number of limited social policies that include a foster systems for the orphans, and a charity-quota for produce merchants.
Discussion of Elestians seems to be a common topic amongst Poseans at the time of the Dreamers Saga, usually right alongside discussion of politics, and is referred to as “Elestiology“. This can include topics such as: why they left, the possibility of their return, their capacity for flaw, their intentions with creating Posea, and other relevant topics.
Technology #
At the time of the Dreamers Saga, the Poseans appear to have mastered glass-working, metallurgy, and combustion-powered trains, but not electricity. This puts their society at a level of development comparable to late 19th century Earth’s industrial-era. Notably, Poseans refer to an unfamiliar phenomena wherein physical contact between some individuals triggers a shared hallucination, which they refer to as “static electricity”.
