We should help

You are still in shock and disbelief. Demons are real. You feel compelled to help Tasha.

"Tasha, can we help?"

She scrunches her face. "I'm not sure how much help two untrained woman can be...what the hell. This mission is a cluster fuck at this point anyway, having your help can't make it any worse."

You are a bit insulted, but you manage to say, "Thanks."

"Ok, the first thing, both of you touch this stone." She pulls out an odd, pale green, crystal.

You and Charlotte both put a finger on it.

"Infernum nos mirandum."

You give Tasha a puzzled look.

"This will make you invisible to demons. Remember, it's only demons. There are a great many humans and other things here."

"Ok, what do we do next?"

"We should probably get out of this stairway, they know we're here. There are four stairwells in this building. We could try find Cassandra and Elise. Of course closing the portal is the most important thing."
