Gemblades

Gemblades are legendary weapons in the story, which several of the character in the Forlorn Trilogy wield.

Concept
Eck created gem blades based off of several influences from other video games he played as a child. He was fascinated by the sword that the character Fo-lou in Breath of Fire IV used, which seemed to appear out of nowhere until he was using it. The gemstone part came from the Jumi cores in the game Legend of Mana; Elazul was Eck's favorite character in the game, and thus he found the Jumi race very interesting. Eck basically combined the two in order to create the gem blades, which were originally named martial gems, but changed when gem blade sounded more straightforward.

Lore
There are 12 gem blades in total, each corrosponding with an element and a God. The gem blades were the god's weapons, which they used in the elemental wars. The gods took their strongest servants and fashioned them into a weapon, using the servent's essence to create the weapon. Once the gods reached an agreement to stop warring with each other, they decided to seal their gem blades away in their old domains on the face of the earth. These weapons were placed in the god's shrine and sealed away in case they were ever needed by the gods again. Eventually, humans discovered these shrines, and managed to find ways to enter them. The gemblades would only respond to humans who bore characteristics similar to the gods who weilded them in the past. When they found a suitable host, they would bind to the host's body, appearing somewhere physically on the host. The host would then be able to summon the weapon. The gem would remain on the host's body until the host was killed. Then it would be spirited back to the shrine it came from. There is an exception to this. If an extremely powerful being passed away, instead of their soul moving on into the afterlife, it would replace the soul that the god originally used to create it, depending on the being's elemental affinity. When this occurs, the new gem drops wherever the person died, and can be picked up and transported, allowing them to become heirlooms. When a new gem is formed, it erases the one that existed before it. The weapon remains the same as far as shape goes, however.
