Did it help fuel Bertha? Debatable. It certainly increased the tides. Supermoons do, and it was a phenomenon understood by our ancestors – those who built the pyramids, those who built Stonehenge. Full moons played a role in ancient belief systems, in water worship, when the guardians of those health-giving Otherworld portals were believed to be able to pass from their own plane to ours. How much more powerful did they become with the onset of a supermoon?
It is this element that plays a pivotal role in the Torc of Moonlight trilogy. It fuels a need to survive in a time that lacks belief. No matter the cost.
