Sorry I forgot to post this, thanks for the reminder Darin.
The storage area within the vault seems to be fairly sizable but it was never very full.
you can easily see where the gold chest was removed. Around the room you find an odd assortment of items:
3 rugs (one with intricate geometric designs, one a single blue colour and one a patchwork of colours and materials)
15 small statuettes (seemingly small carved versions probably commissioned by wealthy patrons, 13 are of humans, but two are of animals... one bull and one wolf)
1 rolled tapestry (depicting a golden city surrounded by blue flames)
3 lead bars (approximately 3 inches by 3 inches by 10 inches)
1 clear crystal box that has ornate gold locks, the box is transparent and the empty inside is easily visible, though the gold locks appear to be locked
3 sturdy wooden chests (one rotting with an oily residue leaking about its base, two intact and with stout locks... one an iron padlock and the other an iron lock with key built into the chest)
1 ornate carved ivory lap desk with writing utensils
2 pedestals with busts carved from some sort of lavender stone
1 odd white leather bag that contains 3 books (1 titled in common "chronicles or eptimus" one that is blank with reddish tinted pages and one with two locks closing it firmly with some form of runic writing on the outside)
1 small statuette of a human sized hand cast in brass or gold
12 sealed scroll cases, 3 marked with a symbol that Zane believes means death, 3 with a symbol that he believes means pestilence, 3 with a symbol he thinks means suffering, and 3 with a symbol that he means penitence.
3 small metal boxes the size of large coffers, each has a hinge but no obvious opening mechanism
1 section of kit that is seemingly exotic materials and incenses (zane believes them to be rare spell components of approximately 5,000gp value)
1 3'x6' mirror on an ornate stand that is currently covered with a gossamer fabric.
18 round black spheres spaced precisely upon a wooden plinth, the area around the spheres seems to have withered/faded slightly as if being exposed to bright light for many years.
a medium sized pedestal that contains 4 potion flasks that glow faintly with their own illumination.
