On the archangel side, Lux was preparing an offensive. He gathered his army, told them when to attack and what to do with prisoners.
He was cold hearted, and intransigent. No one should be against him, and if they were, they'll die.
Lux was a noble archangel, which provided him wings. Most of the archangels were nobles, but some where hybrides, unions from humans and angels. For those, wings were not allowed. But still, he had been married to a demon, and she gave him children, that made them supposed to be hybrides. He had twins, a girl and a boy, but only one of them was a hybrid.
In the demon land and the archangels land, there's a hierarchy, same for the humans. But it does work differently. For the demons, they are ranked by power. Demons use magic, and some of them can be very powerful. Their magic is dangerous and unpredictable, that why it has to be contained with power locks, bracelets they wear to control their magic. The more they have, the stronger they are. Kalei and Azeroth were the 2nd and the 3rd most powerful demons. Mala is the 4th and his daughter Nama the 5th.
For archangels, they are ranked by nobility, if they have wings or not, and the type of weapon they can summon. Archangels can summon six different weapons. From the lower to the higher : shields, cannons, tridents, spears, bows and swords. As you may imagine, Lux is a swordsman.
It almost works the same for humans, it's about their job.
But, Lux's children are hybrid and noble. His daughter, Deby a pure archangel is capable of summoning a sword, but his son, Ray, was such a disappointment when he showed no sign of summoning abilities. But later, they found out he was able to use magic, which was taught by his mother.
The time passed by, and Lux was getting impatient. His sister had to be avenged, he had to act. Without further notion, he attacked the demon land.
