Kharas gingerly continues trying the combination, wincing as he puts the triangle rod closer... closer... click.
It fits perfectly and no electricity charges through the floor.
Continuing, Kharas puts in the square, click, and then the pentagon, click. With the last click a woosh of air rushing into a sealed chamber behind the forge begins to open. The entire forge slides out along the steel panel on the floor. Behind the forge there is a hidden alcove now accessible by moving around behind the forge. In the hidden vault is 2 sacks of coins, 4 golden ingots, 4 vials, and an adamantine plate in the shape of a seven-pointed star about the size of Kharas' hand. Intricate runes adorn the plate.
