Duncan bent down to examine the scene.
It was indeed the nun—the same nun who had spoken to Duncan and Sherry not long ago and who, theoretically, should have been praying in the main hall at the moment.
But now she lay here, dead near the entrance of the Underground Sanctuary, and until the moment Duncan pushed the door open, she had been using her body to firmly blockade it.
It seemed she was trying to prevent something from entering the Underground Sanctuary. However, considering her state before she collapsed, it looked as though she had been desperately fighting against something within the Underground Sanctuary and had closed the doors before she died, to stop that thing from getting out.
"It looks... as if she just died..."
Sherry, bravely edging closer now, peeked over Duncan's shoulder and after two or three seconds, she cautiously spoke up.
