Silver meteorite sand
Sam only had one thing on his mind now. He needs to find a way to use this powder to construct something back. He has a new idea and he could think of many possibilities from it.
But no matter how he tried, he wasn't able to think of a way to make it.
After countless failures, Sam went to the huge cauldron and took out some metals from storage. Since, he wasn't able to do something with the powder, he doesn't want to waste his time and diverted his attention to do something else.
He took out the last remaining bit of the fire bronze. This included the scraps he got from the sheet metal after the circles are cut out of it. He took out the purple gold.
He turned everything into powders and threw them into the cauldron.
He is finally doing something to his two panthers. Actually, he had this intention since they were attacked but he became busy later and wasn't able to find time to make them. Now that he has time to do, he is doing it.
