I kept most of the books I found, if only because I wanted to have a huge library in my Battle Tower. The Tower, however, comes without bookshelves. So all my literary works are stuffed in a pile in my dragon chest. Bummer.

As for your armour, I would advice you to keep the sets you like and sell the rest. I saved a lot of armours and weapons to give to my runners, but that didn't work - you have to buy everything fresh made for them (which costs a fortune). And you WILL get better sets; for one thing, you can loot one fine piece of armour after another, once you
start bumping off Damien's generals in their Flying Fortresses.
