At this time of the year, gnii suffer from the cold and damp, although the action of frost breaking up stones benefits them in the longer term. While some have tried to claim that they are an ill omen, gnii are gentle creatures, their bobbing lights charming at night, and their presence an essential part of the Founders Day celebrations.
Make sure the gnii in your garden are thriving. Put out your candle stubs for them and check that there is exposed rock for them to feed on and play with.
Currently there are a flotilla of gnii feeding by the harbour. They appear to be using driftwood and seaweed, burning brightly and for short periods and falling dramatically from the sky like tiny shooting stars. I wonder if this is how the island looked before the advent of people, and candles.
