Before starting to read anything I want to warn you: the translation of this aspect is not revised. I usually check what I wrote once or twice, but this time it's not like that. Some of the items are translated using Google... something I don't usually do, but these are long explanations (wich I don't have time for translating myself).

Also! You don't need to read any of these pages to understand the story, and I would only recommend reading them if you are interested in something in particular (it can get boring).

Birthmarks surround your arm, runes that indicate your statistics. Strength, agility, intelligence, among others. Your statistics increase exponentially with the increase of a level. Despite this, the experience required to level up does not necessarily have to be acquired by killing beasts.

The level is conditioned by two characteristics that complement two types of experiences

• The physical experience is that it can be acquired by killing another living being.

• And the psychological experience, the one that increases with the passage of time while our vision of the world expands. The more situations you have experienced, the more conclusions and more perspective changes occur in one's life, the more psychological experience you will get.

A great increase in psychological experience is known as "Breakdown", and can make a human being lose their sanity forever.

Before the new imperial system the age was fixed in crosses, each cross corresponding to a total of four years (equivalent to our years). This was used by mathematicians who were at that time direct relatives of the alchemists. After the revolution of the stars and the appointment of the kings a treaty of "Conjunction of Time" was made, where all the countries would establish the same system to measure the time, this being the "Imperial System", created during the time of the crosses. Later the time of the crosses was called "The beginning of time".

The Imperial System can be read in both plural (years) and singular (year) and corresponds to two numbers. Example: 1XIV. The first number (in this case 1) is Opus, and the number that follows is the Arc (XIV). Since in the world there are no "numbers" as such, the number in the present text is a facilitation. Correctly it would have to be "Imma Opus" (the first Opus), while Roman numerals are read as acronyms (Arc Xenta Iva Venti) that correspond to three magical regulations, although for the convenience of the story it represents approximately the same amount of years. 1XIV would be approximately 114 years, although the years are shorter with this same system.

One year corresponds to 5 months, the weeks are not usually counted as such, but the days of the month are counted, being a total of 50. The months in order are:

Opal (or Opalo), Alexandrite, Topaz, Saphire and Ruby.

When a quantity has to be measured or in this case the day, a position measurement is used. "Imma" for example means "The first of / The first / A single" "Aima" means "The second of ...", etc. After the tenth number is added an "X" corresponding to "Xenta". 11 = Xenta Imma. When the second tenth is reached, another "X" is added, which is read with the suffix "Ai" (from a second part) 21 = "Aixenta". When the third tenth is reached, another X is added and the first two letters of the third positional measure are added. Unlike the number of the Arc this does not correspond as much with the Roman number, as they continue adding X until reaching 50.

The last day of a month is called Xentaxia, it is written XXXXX and does not correspond to any positional measurement. The last day of the year is called Maxia. Some countries and kingdoms have their own holidays usually in the passenger language (the most spoken language in the world and the one spoken in the novel).

Finally, the days and nights last less, but there is no time system and the biggest reference to one is the sunrise and sunset.

Yvilash is the third child of the goddess Ayla. It is assigned the third brightness close to the mother star, one that astronomers could not see until the year XX. In the mythology of the astral pantheon he is the symbol of revenge. His death was a snake bite before the beginning of time. In the year 2-XIV he revives as Yvilash (Hero) in Mutua.

Protagonist of the story. He came from another world and was reborn in Mutua. His personality and attitude towards the world is different from the thought that Yvilash tried to portray. He has a great fear of death, but he can not avoid facing it constantly. As a hero he is the weakest, being his initial level -12 and without Hero Skill.
