Now that we have the celestial observer I think it would be perfect to add a celestial augment. Its strength would be determined by the moon phase; Full Moon = Full Power, New Moon = No power, etc. This would come after the celestial observer research. It would only work in dimension where there is a moon/day-night cycle. Also It would couple nicely with the timewinder from Thaumic Wonders.
