Mariel-Taun is the heart of the Vigil. She blesses those who love selflessly. She is the goddess of community, the hearth and compassion. The more you show empathy the stronger we all become. She wishes you to show compassion when you can, protect your community when you are able to, and improve Telara for others.
Mariel-Taun was the matron of lovers, healers, and the arts. As part of the Vigil she reminds us that while we live in violent times, we do not fight only to beget more violence. She wishes us all to take joy in our fellow mortals, revel in community, and take some time to find the beauty and joy that is Telara. We Guardians strive to bring about a better world, free from the corruption of the dragons. The heart of the Vigil wants you to find your love for this world, and to share it joyfully.
