Ghilan'nain kept herself apart from the People. She used her power to create animals none had ever seen. The skies teemed with her monsters, the land with her beasts. Andruil hunted them all, and after a year of killing, approached Ghilan'nain with an offer: the gods would share their power with Ghilan'nain, but only if she destroyed her creations, for they were too untamed to remain among the People. Ghilan'nain agreed and asked for three days to undo what she had made.
On the first day she struck down the monsters of the air, except those she presented to Andruil as a gift.
On the second day she drowned the giants of the sea, except those in deep waters, for they were too well-wrought, and Pride stopped her hand.
On the third day she killed the beasts of the land, except the halla, whose grace she loved above all else.
This is how Ghilan'nain was made youngest of the gods.
