I understand the contents of the message. It looks like Duluke has stumbled upon a big secret, and it has something to do with these crystals. Alba grabs a glass crystal after putting on a glove.
But we don't know why the glass crystals have such powerful energy, or why it's turning the monsters into these undead... things.
Can you please seek out the Mystics of the Senate and ask them these questions? I'm sure they will give us helpful advice.
