To answer your question, my lord: yes, I have indeed heard of this "red lyrium" of which you speak. A single piece of it surfaced in the eastern city of Kirkwall, and its influence alone was nearly enough to cause the city's destruction. As near as we can determine, it is regular lyrium that has been somehow corrupted. Those who have touched red lyrium—or even come near it—report that it "sings" to them, like whispers in the mind that slowly drive them mad.
We do not know, however, what might stem from extended contact with red lyrium. Madness, surely, but would there be a physical corruption as well? What would happen if a mage or a templar used red lyrium as they use regular lyrium?
Far more disturbing is the fact that lyrium could be corrupted at all. Treat any red lyrium you encounter as if it were poison. Do not go near it, do not attempt to destroy it... and most importantly, do not attempt to use it.
