I finally decided to split up some of my dice

The reason my dice back was so heavy turned out to be the 164 Lumineth dice I acquired over 3 editions of Age of Sigmar. They barely fit into the (slightly smaller) dice bag I put them into. I also took out my three different kinds of Imperial Fists dice and put them into their own bag, as well as my MESBG dice going into a little ziplock bag. I was relieved to learn that I hadn't actually lost any of my Rivendell dice like I thought I had, although apparently at some point I bought a third set (I don't know when that happened). The big orange bag (as in a bag designed to hold oranges) the majority of the rest of my dice are in is much lighter now, even though I can't really use it as a morning star as easily anymore.
