"Strike the earth!"
Pickaxe and shovel have long outlived the usefulness of pencil and compass of architects of old. For in these times homes are to be formed by force, rather than will.
Miners are never afraid that their job can be done, as even the walls of the caves are living, breathing, and shifting. Under the Creator's tireless gaze, no place will be without work.
And what a hard job theirs are! One does not simply strike the earth and be done for, safety guidelines are written in blood, and are followed by all!
Firstly, the equipment must be well-maintained: the pickaxe sharp, the mask clean, and a hardhat firmly attached to one's head.
Then, before beginning to sculpt the room - one must make sure that there is sufficient space and support. All miners are on familiar terms with the sounds of the mines. It is enough for them to tap the wall (With the RIGHT thought click with a Shovel or a Pickaxe) to learn whether it is stable, and how far another opening is.
Lastly, to decorate the room and enshrine it's purpose, it is customary to leave a stone toy. To make one, a miner will carve it out of any nearby rock (While holding a stone, and a pickaxe in your active hand, (Focus) + SHIFT thought on what you want to carve).
