BOOOOOOM!
It didn't end with a single explosion. Multiple massive blasts rang out from all sides. When the largest explosion rang out from above, cracks appeared in the sky.
Like a virtual game glitching out, the sky jittered and bugged. Slowly but surely, the sky itself shattered into pieces and disappeared. The image of peace and tranquility that the Shadow Garden held disappeared completely.
When the sky finally stopped functioning, what was revealed to everyone's eyes was the desolate atmosphere of the Outer Wilds. With the artificial sky gone, the Shadow Garden really did look like an oasis in hell.
BOOM! BOOM! BOOM!
The explosions didn't stop after the sky caved. Large blasts rang out across the surface of the spatial walls isolating Shadow Garden from the Outer Wilds. But just looking at these blasts wasn't enough for Damien to determine how they were created.
