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 :)
Really darn good idea. Since each creed is hard, to make it would be excellent for collaboration to create a nice resource here. Perhaps as full subs linked to this one, so they can be voted on appropriately. Go to Comment
A rumour of the knights of some powerful king that sleep until danger threatens the kingdom.
The truth is that they were rebels, trying to split the kingdom. Once captured they were put into an enchanted sleep, protected from age and harm, until their aims have been carried out by others in which case they will awaken.
There is a loophole in the spell in that trying to take one of their weapons will also awaken them.
