The House Cannith foundry is the only intact building in this section of the tower. If the PCs walk around the foundry, they see solid walls and a double door on the western side of the building.   The double door appears to be made of adamantine. The same icon as on the cover of Bonal’s journal spans both sides of the double door, but the same technique that opened the sealed hatch won’t work here. The adamantine layer of the door has hardness 15. This is followed by three inches of steel with hardness 10. In addition, an arcane lock spell and an amazing lock (-6 to Thievery checks) seal the door.   Athletics check: The easiest way into the building is through the gaping hole in the roof. The walls are 20 feet high and easy to scale with an Athletics check.   However they accomplish it, go to the next encounter when the PCs enter the foundry.

When the PCs enter the large open room that makes up the interior of the foundry, read:     Creatures: Two iron defenders guard the foundry. They attack anyone who enters the building. They won’t attack the PC carrying Bonal’s journal, and they won’t attack anyone with the Mark of Making—at least not until such characters attack them. Everyone else is in danger from these constructs.

When each iron defender is disabled, a rod pops out of its forehead. One rod is rectangular, the other triangular. The PCs must also recover the pentagonal rod that is buried beneath the collapsed section of the roof. These three rods are the keys needed to open the hidden vault.   Strength roll: Doing this requires the PCs to remove a chunk of stone from atop the crushed metal dog they noticed upon entering the foundry. The stone requires a Strength roll (-4) to move, and up to two more characters can support to try to accomplish this.

The huge forge and furnace combination looks like a primitive version of the same components found in any House Cannith shop or enclave. The forge and furnace fill the easternmost 10 feet of the room, and metal tiles cover the floor 10 feet in front of the heroes. Three depressions, evenly spaced atop the forge, show a pentagon, a triangle, and a square. The rods fit into their respective depressions.   Trap: If the rods are placed in the proper order, the forge and furnace open to reveal the hidden vault. Each time a rod is placed in the wrong order, the trap is triggered.   Lightning Trap: Shooting d6, 2d6, ROF 1, Range 2", Notice -2, Disable -3   When a rod is placed correctly, it snaps into place and the trap doesn’t trigger. The proper order for placing the rods is triangle, square, then pentagon.  

Hidden Vault

Once the rods are placed in the proper order, the vault behind the forge and furnace opens. The PCs can now take the treasure from the small hidden space.   The following items can be recovered from the hidden vault: sack of 100 sp, sack of 100 gp, 4 gold ingots each worth 50 gp, 3 potions of cure moderate wounds, 1 potion of mage armor, an old map, and the schema.   Common Knowledge: If the PCs find a collector, they can sell the silver pieces and gold pieces for twice (2.5 times on a raise) what they are worth. Finding a collector requires a Common Knowledge check (-1) check once they return to the upper levels of Sharn. The edges Scholar, Aristocrat, or Streetwise can add a bonus to this check.   The old map shows a number of cryptic symbols spread throughout what appears to be ancient depictions of the territory now divided between the Mournland and Darguun. These can be used as hooks for future adventures of your own design; the meanings of the symbols are revealed in the Shadows of the Last War.   Schema: The schema appears as an adamantine plate shaped into a seven-pointed star. It is slightly more than six inches long from point to point, and is covered with strange engraved patterns. It radiates a strong aura of transmutation magic, but it has no magical abilities of its own. An identify spell reveals that it is a piece of a larger relic designed to make a greater whole.
