Hunter stalls, mind racing on her effectiveness in an area devoid of magic. "We have traveled through the Underdark," she begins, "and have encountered many strange beasts and beings. And in our travels, we have encountered something new. Demons, freed from the Abyss by powers unknown, run rampant in these caverns. Truly while we are capable of defending ourselves from the odd fiend, this is something akin to an invasion of this plane. We have even seen the powerful Demon Lords trespass this realm.
"Though your gaze spans all, great and terrible Karazikar, we bring you this warning so that you might defend against this Abyssal threat. We also seek to end this threat, and hope that your ineffable wisdom and sight has the solution to defeat the demons."
To the party, it's pretty obvious that Hunter is trying to buy time so that others might prepare their actions.
