(Where is Osvaldo at this point? I don't know that Meep would start removing Osvaldo's family's items if he was right there in the room. If he's gone, then yes, absolutely, everything goes in the bag of holding)

Osvaldo is in the room with you, Meep. He's eyeing you as you point out everything. "Interesting, Bill must have already snatched it. It was a tome that my father had. It claimed that it was all about vile darkness." 

He eyes the identified items once more and says," If you please, I'd like to keep the mace, greatsword, and armor. Both of them belonged to my ancestor Caladorn Cassalanter and it should stay here. You can keep the bottle and robes." 

Mabel nods and Roland comes into the room with you. When Roland mentions finding Sunblight, he says "I think some dwarves said he's in the City of the Dead." 

Lussa, you hear what sounds like a high-pitched squealing siren-like noise in our mind as you say "and Bill." 

Lussa winces in pain at the noise, shaking her head as if to awaken from a dream.

Meep nods to Osvaldo, and puts the bottle and the robes in the bag of holding. Turning to Mabel and Roland, he says "This is indeed getting complicated, but I personally think the first step is finding Sunblight. Let's find the others and decide what we're doing."

Twitch slumps on the floor utterly bamboozled by the events of the last few minutes.

Delmalis reclaims his bag and nods, "Agreed, but guards first. Maybe we can ask them to help seal the city of the dead while we go inside to look for him? That way he's less likely to be able to escape?" 

(I added those items to my bag for now. We can take the time for someone to attune to the robe if they want, say waiting at the city of the dead before the guard arrive to help seal it? As for the bottle, does anyone feel like risking using it, or wait until another time?)

Sybil let out another sigh as she checks on Lussa, "I guess I should tell Mirt about this when I can," She whispers looks around the place just in case of more trouble.

Roland nods and finds Captain Staget, who eyes all of you. "So what can you tell us?"

The investigation into Aria's attacker. Whoever wants to can give their report, go ahead and make a Persuasion/Charisma check to see if he'll let you leave the party. 

Delmalis nudges Lussa and nods to the captain.

Insight check:  18 to try to get a reading on the captain.

Lussa takes a step forward and shoots a glance back at Delmalis, then shrugs, turning to the Captain.  "From what we've found, it appears that Sunblight used some kind of message stone to instruct one of the children on how to do the summoning.  We do not have any clear motive as yet, but would like to try to get on his trail as soon as possible."  She pauses, still troubled by the image of the dragon, "there is much more going on here than meets the eye.  By your leave, we'd like to head back to the manor to regroup and plan our next move.  If there is anything else you may need of us, or any questions, you know where to find us."

Persuasion check:  9

Twitch looked at Meep for guidance, " Kill Sunbite. Kill Parents. Kill Bill. Kill Azmadass. Take children to live with other children in house we made? "

Captain Staget nods. "Thank you for your information. We'll take a look in the children's room and see what we can find. I'll let you out to find this Sunblight fellow. Bring him in alive if you can."

Lussa from your Insight check, you gather that he's generally interested in getting to the bottom of this mystery in what happened. Even though you scored a 9, you gave him enough information in that he believes you and lets you leave the Villa. 

Lussa nods, "thank you Captain.  Victoro asked us to bring him in alive as well, and we will do our best to do so.  But we will bring him in, one way or another."  Turning to the rest of the group, "shall we head back to the manor to regroup and plan our next move?"

Delmalis shrugs, "We probably need to regroup and plan things out."

"I may have an contact who can provide assistance against this bill character," Sybil whispers to the group.

Twitch nodded back their face still utterly confused.

Meep follows along, and whispers to Twitch "Yes, Twitch. Asmodeus may be a bit out of our league, but I'm on board with everything else. I didn't have parents in the traditional sense, but anyone who would barter their children's souls for power and wealth are inhuman monsters.  And Bill is a knob."

So is everyone going back to the manor except for Sybil, who is going to see Mirt? 

Sounds good to me. Anyone want to go with Sybil?

Meep is too preoccupied at the moment, so he'll go to the manor.
