Walker couldn't help but fall victim to the enthusiasm that the fire spirit had. He knew that it wanted the best possible dwelling and the fact that grey wanted to make the golem core its' dwelling only strengthened the enthusiasm. Now that they were actually going to forge it he would need to be careful that he didn't use all of his mana so that he had some for helping Gil next.
"Hurry up and get that fire going! I want to hotter than dragons' breath!" The elder used this phrase commonly but Midnight seemed more interested in it since she literally had a dragons breath. It was very amusing to her and Walker looked over seeing her snorting a little which he knew was her laugh. He had to take all of his strength not to call her cute in that instant because the fire spirit was waiting for him to help.
The forge orb sounds like a pretty good skill to have.
