Assault on the House of Pleasure

Met with Lazar for more info on Zahara's.
Snuck into the basement through the sewers.
Fought with some guards and a golem in the treasure vault.
Went up to the first floor in an open assault. Killed numerous guards and faced off against their captain. He surrendered and they released him.
Went to the second floor; ran into Amaliel, the succubus from the false temple. She tried to flee but was mercilessly cut down.
Discovered Zahara's lieutenants in their lavishly decorated room and slew them:
- Daemadil Darksong, an eladrin
- Luxi, a tiefling
- Khemthia, a shadar-kai blacksoul
- Khemthia's pet shadow hound, named Midnight
Discovered Zahara gone, but found some interesting information: Zahara Malor and Eliza Corzyr are the same person.
The party also acquired a mysterious, magical, locked and chain-wrapped box in Zahara's chambers. Quinn decided to hold onto it until they could find out more.

Tracked down the lead given them by Lazar at the Ferret House (boarding house) in a dangerous part of town.
Shashank killed him and looted his room.
Examination of the tiefling's loot revealed he had a partial map of Ilmara's sewers as well as garb that identified him as an elite agent of Malcythia.

In an attempt to damage the business, the party decided to try to terrorize Zahara's patrons by killing some and intimidating the rest not to return.
Tried to ambush the two duergar spellcasters when they were passing through an alley on the way to lunch. They were joined by their warrior friend and between the three of them they almost managed to wipe out the PCs, but in the end they were laid low.
Met with Lazar Talamyr at the Horse and Cart pub. He offered the PCs a reward to recover an artifact from the brothel. Also told them of secret way in and promised to give them the locations of four of the five people who left the brothel one evening who hadn't entered originally. Gave the location of one as an act of good faith.
