The Shard's Secret

Summary
The Shards are fragments that Alberius the Founder placed across the kingdom to ward off fiends. They are said to come from an Ilian relic–a mighty armament that Alberius shattered into pieces.
Dialogue
Just what exactly is the Shard? I mean, I know what it IS, roughly, but...
Well, each of the Sacred Shards has the power to prevent fiends from crossing over into our world. They were placed at various locations across the kingdom as a means of defense.
So I can strap one on and march right through a pack of the dirty dastards? I'll take it! Hell, I'll take three!
Only someone who is pactbound with a dragon can transport the Shards.
They're situated in the kingdom's most defiled regions. In order to make sure they aren't moved, the man who gave the world the Shards placed the pact requirement on them.
Thought he was some faerie-tale hero. So that whole saga is true?
He then placed them across the land and made it so only those capable of forming dragonpacts–his descendants–could move them.
But I got one last question. You said the Shards are pieces of one'a the Church's possessions, yeah? What possession was that? A crystal? Some kinda bottle?
Do you know, Zethia?
Whoever wielded this armament held the power to conquer the entire continent in the blink of an eye.
He coulda swung that sucker around and wiped out every last fiend!
But no one lives forever.
Shattering the armament and binding it to the land was his people's best hope. His choices protect us to this very day.
