Vault Shard

A shard of rune essence, refined and manipulated by dragonkin alchemy. Tiny lines, like veins, run through the shard in very specific patterns, allowing the precise control of anima flow through the construction. When used correctly, these shards can create magical circuits, allowing the vault guardians to move, sense and attack with impunity.

It was the dragonkin Lacrussa that discovered this technology and it paved the way for powerful servitors to be constructed. Ultimately she would consider the technology a failure, albeit a useful one.
