The material preparation process for Ancient Undead creation was unlike anything I'd previously witnessed. Over the following three days, I watched the Ebony Tower's most skilled researchers work with components that challenged the very foundations of physical law, each step requiring precision that bordered on the impossible.
The nine-star Void Beast essence required the most delicate handling. Master Valdris himself supervised its stabilization, working within containment fields so complex they created visible distortions in the surrounding space. The essence, which seemed to exist partially outside normal dimensional space, had to be gradually exposed to different types of mana in specific sequences, allowing it to acclimate to interaction with contemporary magical frameworks while maintaining its spatial distortion properties.
