A place used to store items that can be accessed anywhere, at any time. Also known as a Gobbiebag, your inventory is identified as a spacious backpack that you carry with you while you're exploring Vana'diel.
When you start the game it can carry a maximum of 30 items. You can upgrade this amount to 60 through a series of quests:
You can also keep items in your Mog Safe, Storage, Mog Wardrobe, or in your Mog Locker. You have to go to your Mog House to access these items though. To access Storage you have to go to the town you are allied with, and to Al Zahbi or Aht Urhgan Whitegate to access items in your Mog Locker, unless you have spoken with Fubruhn and arranged to have your Mog Locker access available from inside homes in every city.
