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.
With a huge number of sacrificial victims, another realm long ago secretly bound a Prince of the land spirits, Iorstonn by name, thus ensuring the fertility, and improving the magical defences, of their realm. But binding that Prince to one spot has disrupted the weather and magical patterns (ley lines?) over half the continent. Things have become bad enough that a coalition has been formed to rectify the situation, once divinations have established the cause.
Your party is one of the teams assembled to do the rectification: find the binding object and steal it ("so that we can destroy it here in our realm, of course"...*) or destroy it over there. Presumably the Prince will be grateful to his rescuers and angry at the binders, but with a greater spirit like Iorstonn one can never be sure: such beings are "tricksy".
* Of course, the rulers of our realm might want to control Iorstonn for their own ends...
