Helion
From Tardis Wiki, the free Doctor Who reference
The planet Helion was the homeworld of the bird-like Ra'ra'vis.
During each generation of the Ra'ra'vis, the crystalline moons of Helion would align with its sun in the solstice of Pajaro and create an energy beam that lasted for a few hours. It was used to rejuvenate the old and sick. (COMIC: Time Fraud)
