For those familiar with cantrips, you know they are minor acts of magic that have hardly any noticable effect on the world. For example a cantrip to make your food taste better won't heal you any more, or be any more nourishing, just won't make it so hard to get it down. A light cantrip certainly won't be able to blind or even distract anybody, but you might be able flash it to signal someone looking at the right spot.
What if children's nusery ryhmes were a form of cantrip? Like the "Rain, Rain, go away, come again another day." One child singing it wouldn't do more than spare her house a couple raindrops, but what if the whole village got together and was chanting in unison? Each one doing just a bit might actually be able to divert a whole storm...
A possible answer to what happens to spells when a mage dies. If the spell is strong enough, say and enchantment or other permenant effect, part of the mages spirit may become lodged in the magic. It may be a way for items to gain some kind of intelligence, but a mage who has knowledge of this fact would be very hesitant about enchanting anyone or thing. He might have other plans for his afterlife than counting the change in your bag of holding.
Preists, I think, would have this sort of thing covered.
Weapons or equipment that is heavily relied on can be "named". Then the equipment begins to gain abilities beyond those of normal equipment. They might siphon off some of the experiances of their owners (1 to 5%) and level up on thier own. Could be an unintenitional way of creating artifacts. Ships could become sturdier or seem to just barely outrun the worse of a storm that would have surely sunk another vessle, swords could fumble less or resist dulling more, a farmers plow could turn stones aside easier. Anything that is depended on as much as an inividual can depend on as much as another individual could be "named".
Meta energy...lent by lunos of the seven skys, father of the dragongods, has the power to alter events, rippling through time and space, no other form of energy is stronger, with the ability to even destory planets.It rips apart sheilds by going back in time before they were brought up. No weapon can withstand the force of such It is a power usable only by families bloodline, and those we have chosen to gift with miniscule amounts of its power. It not being of this plane, isn't even subjective to the so called "gods" here. Different worlds, different levels of power.
It is a power of change and manipulation, essentially leaving us to create with it what we will, if our mind is strong enough to do so.
Large amounts of this inserted into any one being/energy will cause them to implode, ripping themselves apart and sucked into another dimension entirely.
The limitations of meta are only set by ones mind, an open mind has no limits to the powers of meta.
