Given the lack of specific information, here's a general evaluation:
Aria took the thread, feeling an inexplicable surge of energy. She looked around and saw that each of the townspeople had received their own unique link—a shimmering light, a feather, a drop of dew. Each link was as individual as the person it was given to.
If you follow the paperclip, the bookmark, and the ticket in the right order, you might find the corridor yourself. Or you might, someday, be the one leaving a link for someone else to find.
