From a scroll describing the realm of Baar, Lord of the Six Suns:
Though the light and heat received from the suns was taken for granted for many centuries, they have always been provided by the graciousness of Baar. The elders of Aetherius tell of a time when the sun over the world glowed orange. The sun that currently graces the skies emanates a bluish light that affects the tint of everything mortal eyes can see.
History
Mortals first became aware of the presence of Baar during the Demon Incursions that marked the beginning of the Age of Desperation. As the Clerics prayed for help to stave the attacking Demons, Argentinus Damaun led the demons through one of the gates of the city. As they closed the gates on the Demons a white flame shot down from the sky melting the hinges of the gate and welding it shut. Though it has never been confirmed that this was the work of Baar, their belief that it was is unbending. To this day, rubble lies outside the Demon Gate of Antioch and a fire burns to keep the Demons at bay.
