Description
Concentrated blight crystals?! What could this Drakuru be up to?

Clearly, he's working on something important. Continue to do his bidding and perhaps once he's more familiar with you he'll reveal his plans.

In the meantime, we need to have a look at these crystals.

While you're in Voltarus, try to get some samples of the harvested crystals when no one's looking.

Be alert! Handling those crystals can trigger your disguise to fail.
