Good one to bring up, Val. But I noticed something very odd here... and not do to with the submission itself. Take a look at when this was last updated. I'm sure I'm not the only only one who sees something wrong with that.
It appears Manfred is some sort of time-traveller. Good job, Man.
I agree with Axle, the tone really makes this sub. It was a fun little read; the kind I enjoy. This is another great little gem brought to the surface by the Daily Highlight.
Elemental Gems though... Harnessing the power of nature in a pretty rock. I really like that it isn't just a magical amplifier, it's affects nature. This either implies that the mages of the setting manipulate nature itself, or that this item is more intended for nature-themed spellcasters (Like Druidic or Shamanistic types).
Too often we see Magic as a force that binds the world together, I think. This piece makes me see a world where Magic is a byproduct of the natural world. To make a flame grow, to increase the force of a previously gentle breeze, summoning storms, calling lightning strikes, altering river currents, rapid plant growth, and such.
Good stuff, this is.
