The weapon has elvish writting on the hilt, which describes the power of the blade and a warning to whomever may use it. the main users are elvish warriers and members of a royal family as it is normally handed down a family line. The blade is made of platinum which shines mother of pearl and when commanded to it can submerge itself in boiling water which can get up to 110 degrees. The attacker can not withstand the blade near them or on there skin, as the blade enters the body the boiling water will burn them from the inside out within a matter of seconds.
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.
