Kai's duty as a member of the Human Protection Agency is to ensure that the four races from The Great War are kept sealed in their graveyards. Humanity has been at peace for 100 years, until one day a portal opens and the world he's known ceases to exist.
We took the underground space 
that was still intact
استولينا على المساحة تحت الأرض
والّتي كانت لا تزال سليمة
Ein unversehrtes Untergrundareal,
das zu einer Stadt umgebaut wurde.
Nos adueñamos del subsuelo
Nos hicimos con el subsuelo
On a arrangé le métro
pour en faire une ville souterraine.
Abbiamo fatto nostra
la zona sotterranea ancora integra
Pegamos o espaço subterrâneo
que ainda estava intacto
Переделали уцелевшую подземную конструкцию
