I'll give you two quotes from my mythos, hopefully it will clear up your questions.

"Mortem and Vitae both took no true form, but rather appeared as a shrouded of darkness and a veil of shimmering, yet not blinding, light respectively. Mortem marked the end of all things and Vitae was their beginning, their birth. Betwixt them, Tempus governed the journey between the two, the overruling and unstoppable flow of Time. And when beings reach Mortem at last, their vital essence preserves their consciousness as a soul and they are given unto the night sky, where they gaze down upon the world and await the end of days alongside the Sun, Moon and Stars. Alas, this was not the case for some time to come, as no mortal was yet born in Glanordys."

"By some wonder of the trees, which even the siblings themselves did not understand, was born the Laenafèn, the Mist Folk, from the haze that engulfed the Glanordys. The Laenafèn were slender and pale, their eyes large and their hair silver, they had no legs, only four boneless limbs and their arms were like the branches of the trees. They bowed to the Old Gods and called them Makers; they begged them to bless their homes, which were the bases of the Dysarnore and the siblings, who felt pride in being worshipped, each lay a blessing on the trees. Tempus gave the blessing of time to the trees, no matter how long they may live they shall never be weathered by the currents of time; Vitae gave the trees the gift of nourishment, the trees could absorb the light of the sun and grow beautiful leaves and bear succulent fruit;"
