"The Celestials Around The Transition Island"
As for the war strategy and such...Wilhelm believed that his brother would be the one handling this, and he might have already implemented his plan right now.
Indeed.
A few hours before the war started, the merfolk had sent their troops to guard the sea around the transition island and the beastmen occupied the other islands not far from the transition island.
With this, the celestials wouldn't have any other places to rest other than on the clouds.
But the flying-type beasts and monsters they had tamed were all ready to disturb these 'angels' among clouds.
It was soon to be nighttime outside, but this was exactly why Wilhelm had a hunch that the war would start in just a few hours.
Their blood clan members were creatures of the night, and they would be more powerful when it was dark.
The celestials must have planned to wait until tomorrow when the sun went up, but the blood clan's king might not give them that chance.
