The students of the first-year hunter class bubbled with mixed exclamations of awe and utter repulsion as their eccentric female professor walked through the class holding a transparent jar for all to see.
The jar she held was tightly sealed with a myriad of clothes running around its mouth, embroidered with golden runes that gave a gentle pulse.
Opening the jar with brute force was said to be harder than splitting a rock open with one's head. Of course, this was only an expression. Opening this jar without the right knowledge of rune theory was about three times harder than splitting a rock with one's head.
Inside the jar, a dark brown ornate crucible held peculiar purple objects. Three oddly shaped rocks glistened with a purple glossy sludge covering them.
