Perhaps the point which is the easist to implement is:
"Unlike the transporter, magic items don't seem to break or stop working very often."
This strikes me as the best place to address this! No item should be 100% reliable. There should be cavets to their use, costs and unforseen consequences. How many magic items in folklore were bug-free or 100% safe? Go to Comment
This is a great complication to add to one's NPCs. As long as there has been stuff to mess with one's head, there have been those who imbibe in it. While a mature theme, it is essential if you want to have a 'realistic' world. Go to Comment
I view messing with time measurements a somewhat low-reward activity - you may add flavor, but you put a new layer of translation between how we are used to reckoning time, and the game world. Worse still since the game rules themselves, unless you are using a home-brew, will also use real-world time.
I see Dates as much more flexible on that front, but messing around with hours or smaller strikes me as somewhat masochistic. I'd need a really good reason for that :)
Jemas Lorne, the most celebrated poet of the age, was found dead, clutching a fragment of verse torn from his journal. The tantalizing fragment spoke of wealth:
Golden sands, empty and cold,
Treasure's crypt, forgotten gold.
Under stone, ancestor's doom,
Noble's prize, troubadour's tomb.
Rumours claim that the poet's father, an eccentric nobleman, had hidden much of his wealth before his death. Perhaps the missing journal has more clues?
