Killing Tools

Sunny landed on the obsidian dust in front of the gargantuan Serpent's skull, which towered above him like an ivory mountain. The lower jaw of the immense creature was buried in the dust, but its upper jaw loomed above him like a dark portal, its arch adorned by a palisade of great, terrifying fangs. 

Sunny let his wings crumble and dissolve, then allowed himself a few moments of contemplation as he studied the ancient remains. 

He had a good idea of whom these bones belonged to…

They were the bones of a Soul Serpent. Not the Soul Serpent, but one of its kin. 

It made sense that Sunny was not unique in having received the companionship of a Shadow Guide. In fact, Soul Serpent was too perfectly matched to someone who had received the blessing of the God of Shadows — so, Sunny suspected that all those marked by Shadow God were bestowed a Soul Serpent of their own.

Just like those marked by the Lord of Shadows received a small shadow snake.
