Bank

From AEWiki

Your bank is where you store the items not held on your avatar or in your backpack. Each character on an account has its own bank. The bank has a limited number of slots but this can be greatly increased by the use of containers such as bags, crates, chests, etc.(crafted or store bought). Most towns have a bank with NPCs called "bankers". Click on the "banker" to access your account and withdraw or store items. If you have a house you can obtain a deed for a "vault" (which are crafted items), which is added as a permanent fixture in your house. All characters on your account on that server will have access to their banks via the "vault" in your house. Anyone else who you provide a "key" to your house cannot use it to access their bank.
