Brought to Heel

I have fashioned a tool from the chain links you found. You might call it a "lasso" of sorts.

The energy within this chain is best suited for binding demons, but seeing as Calefactus may be from beyond the dark portal, I suspect it will work on him as well.

If you take him down bring me a sample of his fel lifeblood. Such an anomalous being warrants further study.

Calefactus' current location among these wastes is unknown, but I trust you'll track him down, <class>.
