Six thousand meters up in the sky, an enormous structure measuring three hundred and eighty-eight meters from top to bottom floated silently, concealed within thick clouds.
This was the headquarters of NESTS, the Sky Mother Nest, which Ignis had commissioned someone to design according to his own vision.
The Kronos Kingdom had taken quite some time to build it, and the project had been a test for the kingdom itself.
After all, the Sky Mother Nest was far more technologically advanced than the Sky Arena, especially since it required the application of several cutting-edge technologies.
Putting those technologies into practice during construction had also brought the kingdom considerable gains.
Half a year after the theft of the heavenly tribute, the Sky Mother Nest had been successfully delivered to Ignis.
It flew by controlling magnetic forces, could rise to an altitude of twenty thousand meters, and could also descend a thousand meters beneath the sea.
The exterior of the Sky Mother Nest featured optical cloaking technology. Even without clouds to conceal it, it remained invisible.
For anyone hoping to enter the Sky Mother Nest, simply finding it posed a major problem.
For the organization as it stood, a headquarters was not particularly useful. There were too few members, and the key members all had their own assignments.
Only some members and the research teams headed by Doctor Ian and Doctor Miguel had relocated to the Sky Mother Nest.
After recruiting over this period, NESTS' research team had expanded to more than fifty people.
Though it seemed difficult, boarding the Sky Mother Nest was actually quite simple.
Doctor Miguel's combat suit had a cloaking function, while special boots allowed the wearer to fly into the sky.
Once authorization had been confirmed by headquarters, special glasses could pinpoint the Sky Mother Nest's location.
