Ooookaaaay i shall explain a few things. its my fault i should have specified stuff sooner but here goes nothing!
Weapons and magic allowed but nothing too huge
it is fantasy
R rated but dont go crazy
era is modern
The shards the protectors wear look like simple pieces of jewelry (ear ring, bracelet, necklace etc.)
You guys can start your characters out anywhere on earth but keep it on earth
The shards have the ability to heal the protectors of wounds that only be considered life thratening otherwise they heal like any other person
example: protector gets in car wreck, they lay on the ground with their entrails laying on the road, shard glows and everything is put back in its place, entrails and body completely fixed as if nothing happened
now then that should do it unless there is anything i missed
