Each passage through a CRT screen leaves phosphor afterglow that persists across multiple displays, creating a luminous trail visible only to those who've completed at least three simulation crossings. The electron beams of connected monitors synchronize their sweep patterns when a pilgrim is present, creating distinctive interference patterns that serve as both passport and progress indicator. Players who complete the full 16-simulation pilgrimage develop what the system calls 'phosphor resonance'—a permanent electromagnetic signature that causes any CRT within range to display their attendance record in the overscan region beyond normal viewing area.

It functions as both journey and judgment—the phosphor trail you leave across multiple CRT screens becomes your permanent record, proving that in the Chaintrix, traveling between simulations isn't optional strategy but mandatory pilgrimage for those who seek to understand the full scope of the survival system.
