So basically, the world in this book is another Earth where creatures from fantasy exist and live among mortals in the kingdom, Aidovalon Kingdom. 

The Aidovalon Kingdom is a Kingdom where magic and technology meet and the kingdom is led by a King with the help of his advisors. Princes are to take the throne after the death of the king in the kingdom but if there are no princes but princesses, then the princess has chosen by the King before his death is to be the next Queen of the kingdom. 

There are two academies in the kingdoms, Twilight Academy of Heroics and Arcadia Academy of Villainy. Although both academies are different in terms of name and syllabuses and many more, they both focus on the success of the students in their own lives in the future. For students who graduated from both academies, they will either go to the respective universities, Twilight University of Heroics and Arcadia University of Villainy, normal universities in the kingdom, or they will just start working in the kingdom. Students in both academies start their college syllabus at the age of 18 and finish their college syllabus at the age of 20 which at the end of the year after the results of the finals were given, the students will graduate and will be able to start working.

To know whether the potential students is chosen by the academies, the students just need to check their emails and their mails. The official emails will tell the student that they have been chosen and the mails will show them their one-use pass which the students will use for the physical exams and the written exams.

The number of students accepted for each of the both academies will be 200 students and the first 100 accepted students are those who have passed the exams with flying colors and the other 100 are those who have passed the test with normal results but have something that catches the interest of the headmasters/headmistresses of both academies. ( What I mean is that if a potential student of Arcadia who gets normal results have a really good affinity in Fire elemental magic, for example, the headmistress/headmaster of Arcadia will accept the student.)

For the exams, the students will be separated into two groups, the first group will start on the first day of the exams while the second group of students rests on that day. Then on the next day, the second group of students  will take their exams while the first group of students take a break. After all the exams is finished and the students go back home, the teachers will calculate the marks out of hundred (physical exams and written exams are all over 100) but for the total marks (the combination of the two), the percentage of physical exams is 60% while the written exams is only 40%. Once that's done, the teachers will eliminate those students who doesn't pass.

For the next step to be a student of both Acadia and Twilight academy, those who had passed are required to go through an interview and another test (the first test is individual test (fighting against their instructor one on one or assassination test or random test while the second is a test on teamwork) to prove that they are eligible to enrol into the academy. If are eligible, the potential students will get an email, notifying them that they are eligible to attend the academy and will be sorted into two groups, one group is those who passed with flying colours while the other is those who passed with normal results and the potential students become actual first year students of the new school year.

P.s: the exams, interviews and other stuff will be done during the holidays, which starts from the beginning of November till the end of December, and those who wants to go to their dorms early will start going to their dorms at around 2nd to 5th January and the rest will go to their dorms at 7th of January. School year starts at 10th January every year and ends at the end of October before the start of the school holidays on November.
