The Lodestone Heart was not absorbing everything that Kimat was giving it as if it was very selective and had a mind of its own. Adrian just made sure to watch everything as that is all that he can do. He will need to trust Kimat to be able to solve this, but he will step in should the need call for it.
Kimat's lightning was silver in color which is different from the lighting that the Azure Dragon of the East calls upon. This made the fusing stage with the Lodestone Heart a bit challenging as there were different attributes. The remnant energy of the Azure Dragon even became sentient for a moment as it started to fight off Kimat's influence.
The remnant energy of the Azure Dragon took the form of a lightning lizard. Adrian would have called it a dragon if it was at least one foot tall, but it was as small as a lizard. Kimat asserted his dominance and overpowered the lighting lizard until he was able to devour it.
