Vahdrak

Vahdrak is the Chaos Eldwurm. The remains of his species were used to imbue the cuirass of Kaden's armor with a chaos dragon's power, allowing him to phase out of reality and teleport over short distances; as well as summon his helm from a dimensional space. Judging by this display of powers, it is possible that the Vahdrak himself is capable of doing the same thing because he is the oldest and most powerful among his species.
