〖 A mirror, and a candle 〗
'Negary' was holding a mirror in his hand as he stood in front of another mirror, between his mirror and the other one, there was a single lit candle.
The Droste effect referred to how a picture recursively appeared within itself, giving off the effects of an infinite loop.
The mirror in front of 'Negary' reflected the image of 'Negary' holding a mirror, but the mirror inside 'Negary's' hand was also reflecting everything, so as one looked closer and closer, one would see countless 'Negary'.
The flame of the candle slightly flickered, but within this infinite loop of mirrors, it appeared as if there were an infinite number of candles flickering.
