Kran metabolism is very complex, they are used to eat sand of various and precious minerals that are digested in their stomach thanks to strong acids. They can also eat food full of mineral salts like seaweed and some crystals created in their kitchen, similar to chemical laboratories.
Well as you can see crystals appear to be easily digested by Krans, so i dont think you would only have to eat 1 crystal a month, this might apply for a dwarf XD XD XD. (of course it would probably take years to digest inside any other races)
Also the last part of that about the crystals made in their kitchens and chemical labratories makes it sound like Krans have a crack problem. >< haha just my 2 cents.

Yep seems to be a big Rock thing goin on. ROFLMAO
Im sure we will get some light shed on the story once the game progresses a bit ^^
