Luck Points are Fate's way of showing interest in the PC's, and the GM's way of rewarding the players.
Given the difference between fantasy and sci fie subs, I am proposing a voluntary Rating system
Steamery is a type of learning, like Magery and Lettery (Magic of Written words, Scholarly works), akin to Alchemy which combined elements of the two. It is considered a type of magic, the use of the four basic elements to produce “magical” power.
Hathalfar holds the writhing troll down with his gloved fist and sword. The beast squirms at the touch of metal. “How far is Kolm?” he demands for the third time. “I said! A long way away,” replies the troll.
The measurements on Arth center around The Emperor and the Imperium. The Imperium imposes certain standards upon its subjects to make communication and trade between areas easier. Some of the most important was how much each coin was worth (and its basic size), the common language (imperial-low and high), and a system of measures.
Arune Spheres are hollow, blue reflective metallic spheres about 25 cm/ 10" in diameter (though some are larger). They are made of a thickish glass mirrored on the inside. When magical energies are flowed through the sphere, it produces a haunting tone, which can be varied by the type, intensity, and harmonics of energies passed through it. (It sounds like an electronic organ.) If multiple energy flows are generated, multiple sounds can be generated, some of which sound like mundane instruments. Masters of The Craft can replicate almost any sound in their memory with one. Though originally used as a training tools for those with The Power, it has been adapted to be a musical instrument. All it takes is someone with patience, medative training, and a touch of the Power, to use it. (Thus becoming the favorite instrument of anyone who was tested to the first level of the Craft, but failed to advance).
