'All shall fade when darkness comes! All shall burn in blackened flame! All shall run in terror flee! When the dread lords servant is summoned in royal blood!' Xanthus repeated the words to himself mentally, pondering them even as he was watching the scene unfold beneath him and far away to where the caravan was. The high-pitched screaming was audible even to him from his distance, and he knew that the princess was taken. 'The Dread Lord's servant...summoned in royal blood.' The knowledge came to him in nothing short of a tidal wave, crashing against his mind and providing it with perfect clarity.
Blood was used on occasion in conjuration, particularly when something truly powerful was the subject of the summoning. Royal blood, being endowed with more magical worth because of its higher value to humanity, could theoretically be used in the summoning of truly legendary creatures. Being that the witches proclaimed that their goal was to summon 'the Dread Lord's servant,' Xanthus's mind immediately knew which one they were after. He could hear the name calling out to him from his blood, the intrinsic link that he shared with Kyros. With the acrifice of a princess, whom else would they summon but Kyros's enforcer.
"Mulgath."
For a moment after the clarity struck, Xanthus stood still and let that thought settle in. The witches were making their way out of the carriage with the princess, cackling as they began to shadow step into the woods. It was then that Xanthus noticed the small child. His mind focused on her and on her sword, and an idea began to form. Several ideas, actually. There was a chance that he was correct, but he always preferred to have back-up plans. Turning his black gaze fully downward, Xanthus spoke to the 'child.'
"Child-like in appearance, but with pale skin, dark hair, and most importantly, red eyes. You are no child at all, but a Vampyre. A Vampyre with light magic, as impossible as that sounds. So, will you give chase, as the sphinx does? He does not know it, but he stands no chance against what he faces alone...and of course, if he dies, then I imagine that the princess will die...and doubtless that means something to you, else why would you help us?"
Ignoring the child-like Vampyre's comments and questions, Xanthus stepped through the shadows and began to follow the witch's trail. 'To me, Dread Wolf, to me!' The Alpha Dread Wolf would howl and break away from the combat, venturing around the battle to avoid both caravan guards and Dread Wolves in its effort to follow Xanthus swiftly. 'Undead warriors, return to your rest!' The undead fell apart and returned to death, leaving the caravan guards to face the remainder of the Dread Wolves alone. 'There, that should provide time.' Xanthus would step through the darkness from then until he found the witches again, following both the sounds of their cackling and the feeling of residual shadow-based magic as they made use of similar travel arcana.
