The Equinox Family
The Equinox family only appeared in front of Magi twice every year when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the centre of the Sun being in the same plane as the Earth's equator. The day and night are equally long and sometime born from them are hybrid of those parent. Would you be lucky enough to get that hatchling which happened only twice a year, symbolize longevity where the day is always continuous.
This is only a pegasus lineage
