For now, all you have to determine what's important or magical is Detect Magic, Loremaster Knowledge Checks and some basic experimentation.
A quick inventory:
A rather large supply of weapons and armor from your fallen foes, including slightly magical mitheril shirts, unenchanted adamantine breastplates, slightly magical repeating crossbows, several of those odd polearms that the vampires were using, 1 magical Cloak(eventually determined to be Resistance +2), one amulet(Eventually Determined to be natural Armor +2), three sets of bracers (Eventually determined to be 2 of Dex +2, one of Armor +2).
The falcion that the Orc was carrying is recognized by Akharos to be one of the Razors that the orcs order carries. He takes it (Its +1, with keen and another +1 if its weilded by an orc).
Kelnar examines one of the polearms close-up. They are made entirely of adamantite and have different heads with different functions. One side has a wide sword-like blade, the other a hook with a spike behind it. It radiates some pretty strong Shadow Weave magic and emblazoned on its handle is a sigil that appears to be the holy symbol of Shar rendered into a toothy, fanged blood-dripping maw. After some thought (Lore Check) he remembers reading about a Shar-worshipping vampire lord named Enkivik who rose to power in the North about a century ago, whose vampire army took overran a small inland town and threatened to expand further until they were defeated by forces collected by several nearby powers. Enkivik was said to be destroyed in the battle. It is possible that his armies could have wielded such a weapon
On the wall to the north is a huge iron door with a tremendous wheel on it. It is apparently a safe. Thats probably where the valuables are.
Kelnar finds a magnifying glass on a table that appears to read magic auras and translate documents.
Kelnar recognizes the black domino mask sigil to be the symbol of the Night Masks, a very powerful international crime syndicate that is rumored to include many vampires, particularly on the upper levels. It is not traditionally officially affiliated with the Church of Shar, but being that Shar's portfolio includes darkness, murder, secrets, and vampires, it is likely that many Night Masks would choose to worship her.
The documents on the tables are quite diverse, with each desk seeming to be working on a different project. The researchers that worked here are all dead. they were strewn about the room that the demon fled through, all burnt to a crisp. It must have happened after thy fled but before the demon appeared, but you don't know how it happened.
Further analysis shows several distinct projects.
1. Financial Research -- contracts and papers detailing debts and financial holdings of various lords and businesses are found scattered about the desks, shelves, and cabinets here. In most cases, the lord or company in question is deeply in debt, so this is probably part of some sort of blackmail or loan sharking scheme. At another desk are similar papers, seeming to be copies but having differences. Apparently they were forging documents.
2. Troop movements. Maps of troop movements for armies on both sides are recorded here, as are notes, apparently from talking to soldiers. There is a letter that has just been written, talking about increased elven activity in the seas near Luskan and in outlying areas. It ends, "I recommend that defensive measures be stepped up in and around Luskan, and the construction of the Stormships sped up as much as possible. The movements themselves indicate that there may be an invasion within the next few months. When I meet with my source in a few days, I will be able to determine more." It is not yet signed, but it is addressed to a High Captain Grorgodorl Lindo. None of you know the name, but it doesnt seem to be Luskanite. You find that on one set of notes, it speaks of a meeting at a vacant apartment in the middle of town (It gives direction on how to get there) at midnight tomorrow night with "a good new friend of yours."
3. Medical Information -- It appears that this individual has been studying reports about methods for increasing the efficacy of various drugs and poisons.
4. Reports about various violent incidents around the North. A letter, also in-progress, notes:
"At this time I can safely say that the Council is being reconstituted. Any of the following individuals, and possibly the organizations that they represent, could be the one who is behind it. From what I hear, this is operated by a single individual. Any of these could be involved in some minor way, but only one is the leader:
Renyn Aolis - leader of the Eyes of the Wood, Evermeets excellent intelligence operation
Randal Morn - rebel turned Dalesman lord
Caladnei - Advisor to the Regent of Cormyr Alusair and Royal Magician
Hovarn Turg - leader of a Waterdeep-based problem-olving agency
Irusyl Eraneth - Skullport-based drow leader of a similar organization
Vlam Wiso - intellegence chief, Algorondian Military
Fenton Karfon - adventurer, presumed to be a master Harper"
Found among the equipment of the BB is headband radiating very powerful shadow weave magic and a packet of papers. They detail his orders to raid Irusyl's base in Skullport, kidnap Jaina, and take her to the temple of Gond in Luskan. It included a map to Irusyl's base and other useful operational information. It also states that a payment of 50,000gp in unminted gold bars could be collected from Lady Thiste Thalavar in Yartar as payment.
