The city guards were alerted. Everyone made their way to the gate and the walls.
Not just them, many curious people made their way too. Some thought more and sent their bird puppets and that triggered a chain reaction.
Everyone sent their bird puppets to get a clear view of what is happening.
But all of them could only see the dying forest and vegetation. They could hear the hooves of the horses, but they couldn't see anything other than the moving masses of black.
The city guard captain was alerted, but by the time he came to the door, the shadows already reached their destination. Everyone including the captain heaved a sigh, but also felt nervous at the same time.
Because the destination of the shadow is obviously the Hub. And right now, they are at the closed gate of the Hub and they also converged back together into a single mass.
It moved towards the door at an incredible speed trying to crash it down.
