Blessing of Light

The Blessing of Light is a power bestowed upon Warriors of Light chosen by Hydaelyn distinct from the Echo. The Blessing of Light is tied to and further empowered by the Crystals of Light obtained by Hydaelyn's champions, who manifest these crystals by their deeds.

The Blessing of Light provides protection from aetherial corruption, such as tempering by |primals, wards the allies of Hydaelyn's champions against intrusion by Her enemies (though the three Ascians of the Source are capable of bypassing this), and allows Her to intervene directly on their behalf to perform miraculous feats.

During the Warrior of Light's adventure in the First, the Blessing of Light was used to absorb the power of the |Lightwardens. However, even with a fully-empowered Blessing of Light, the Warrior of Light was unable to fully withstand the primordial Light absorbed from these creatures and almost succumbed to a sin eater transformation.

In Final Fantasy XIV: Endwalker, the Warrior of Light learns that the Blessing of Light is actually a spell called the Traveler's Ward cast by the Ancient Venat, the true identity of Hydaelyn and former holder of the seat of Azem. The ward specifically protects against aetheric corruption, and the magic is unique enough for the Venat of the past to recognize it as her own spell despite bestowing it on the Warrior of Light millennia in the future.
