In Peadar Ó Guilín's the Call series, why did the author choose for the Sídhe to steal teenagers away to the Grey Land for exactly 3 minutes and 4 seconds? Was this length of time, or proportion of a day, chosen because of some kind of mythological resonance? Or is it just a random short length of time?
The author answered the out-of-universe reasoning in a series of tweets in 2016.
Q. How long is a day in the Grey Lands? Also why is it 3 mins and 4 seconds?
PÓG: Nobody really knows. It feels like a day, but is it? 3 minutes and 4 seconds was a decision I made because I wanted it to be long enough for tension to form, but not so long for tension to run out... Not a good answer, I know ;)
In universe, the amount of time was because the Sídhe don't use human time measurements.
Q. "3 minutes and 4 seconds" seems very precise. Was there a specific reason this amount of time was chosen by you?
PÓG: Not really. I didn't want it to be exactly three minutes, because, why would the Sídhe use our measurements of time? That's all
