Update 0.4.2:
New Protector tenants have been added, but are not spawnable. Certainly not after you get the postcard from Esther, I should think.
All links to Wolf's Pottery Mod severed; the ability to craft said objects has been spun off permanently to Frackin' Patches.

UPDATE 0.4.0 - Geothermal Compressor mod
The Geothermal Compressor is finally out and can be used to create an even larger number of nautrally occuring blocks. Only players with Starbound Awakens may build these, but scout around the universe enough, and you may find one.

You now have access to the world's largest Pottery mod for Starbound to date, as well as access to content from Fevillian's Craftable Smashables and Jay_Rab's MYOS mod.

UPDATE 0.3.3
Fixed a bug that could potentially crash your game, the issue was caused by a buggy recipe. Thanks to endertrot for spotting this!
