Titan-Forge now has their Daemonic Wasteland bases available over in their webshop.
From the announcement:
One of our fans suggested that we should release the Deamonic Wasteland bases in addition to our new Deamonic Kingdom products. We’re more then happy to oblige! In addition we also added few bases we were working on for some time! Now you can add some variety to your collection with just few purchases! Check them out on our website
