I hoard everything, in my OCD storage system. Gems, gold ingots, silver ingots, goblets and silverware make up my treasure safe. Unenchanted jewelry make up my other safe, then enchanted jewelry, then I also have ores, common ingots, expensive ingots, things related to building houses, things that are taken from animals such as pelts, hides, leather, strips, tusks.
I have a chest that holds robes, staves, dragon priest masks, faction armors/daedric artifacts. I have a chest for enchanted armor/unenchanted glass, daedric, dragonbone & ebony because they look magical. Also have the same for enchanted weapons.
Then I have a chest for soul gems, another for potions, then another place for all alchemy ingredients. I have a safe for tomes and scrolls, my spiders that I throw at people, spot for linen wraps and those ancient draugr (sp?) tools.
I must have everything. I mean, with several million septims and thousands of gems. I'm allowed to be crazy, because I'm crazy rich. I could buy a province, possibly a few Elder Council seats...
The reign of the Tyrant Just Emperor, DrunkenMage will soon come.
