In the past timeline, the spire is crawling with monsters and the scourge has already taken over that it would look disgusting just from its figure alone. Since the situation from the past timeline didn't occur at best, I am not dealing with monsters this time around but angels who are still sane and have the knowledge to fight back, unlike monsters who just move on their instincts.
I looked up at the spire. It looks like it was made of bones of several creatures but when you look at it closely, it was just made of metal and different kinds of rocks. It just looked like that because of the wear and tear. Perhaps the spire is something that has been existing since ancient times and it doesn't look like this in the very first place.
