In fairy tail, we know that the third generation dragon slayers have been taught dragon slayer magic by dragons and also that they have dragon lacrimas implanted.

I agree. They are Dragon Lacrimas, and not lightning Dragon Lacrima or shadow Dragon Lacrima. D'après Seila, la puissance destructrice de cette lacrima serait 500 fois supérieure à celle de Jupiter. The Dragon Lacrima, where do they come from? I was wondering if it would make sense for Dragon lacrima to be dead dragons (like the Exceed lacrima in the Edolas arc) Because if so then the theories that Sting and Rouge's Dragons are inside them like Igneel would be incorrect as they have their own Dragon's lacrima inside them. r/fairytail: Fairy Tail is a whimsical and adventurous anime, full of Wizards, Dragons, and Talking cats! Lacrima du Dragon : ... Cette lacrima, appartenant à Tartaros, est confiée par Seila à Elfman afin de détruire la guilde Fairy Tail. If a dragon lacrima of an element of different type is implanted what will happen?
