well, you prolly have some stuff you want to hold on to, but don't want cluttering up your inventory. time to make the acquintance of the vault, which you will become very familiar with. as an experienced gamer, i am sure you are familiar with the bank or vault concept, and istaria's is no different. it is personal storage you can access from many places within the game, including on your own plot/lair.
on new trismus, you will find the vault in the main town. from the dragon caves, head up the road. once you reach town, you will see the three buildings in a block on your left. the center one with the moneybag sign in front is the vault.
enter and head to the back of the building. there you will find serena, the vaultkeeper for new trismus. greet her and listen to her talk. keep the last part in the back of your mind - she is telling you how to get your vault upgrades. when she is done, right click on her and choose open vault.
once you know what's what, you can start to move items from your inventory to the vault. open your inventory, click (to pick multiple items, hold the ctrl down while you click) and drag from your inventory to the vault.
close your vault and you can get back to bizniz!!
that's it really for the vault, so head back to kerian and get your next quest! find out more next time!!
