Goblining
Seeing Longtrouble's peaking interest in the rock Hao Xuan quickly washed his hands of the matter. The feeling he got from the 'Midas Touch' was far too vague to bet with any level of certainty.
But Longtrouble was feeling every nook and cranny on the fist-sized piece of debris trying to study and analyze it.
"Let's do it, I will go with this one. I have a good feeling!" he mumbled in a trance.
Hao Xuan frowned at his odd behavior. The goblin appeared to be enamored by the rock and he knew better than to come between a hungry creature and its meal.
"Fine, it IS your money. Just remember I told you there was little chance of it being valuable."
"Yeah yeah I know..."
Longtrouble shooed him away and brought the rock to a glass case about 2 meters wide and 1 meter long. He lifted the front panel and placed the rock in the center before tapping on the rune located on the exterior of the glass case.
