Seller of Rare and Taboo Goods

Elaina was not expecting to hear it. Taboo goods and even rare goods that cannot be purchased anywhere? And on top of that, this wandering merchant also buys goods that catch its eye.

"It seems you are not believing me, are you? Well then, to make sure you believe me, here, have a good look at one of the things I will be showing you."

The person or entity inside the carriage rummages inside before putting out a tray containing a red jewel that exudes a very ominous aura. Just from the aura alone, Elaina can tell this is one of those "taboo items" that this guy mentioned.

"This is called the Gem of Draining. This gem drains the life of whoever, or whatever lifeform it touches. It can only be used once but this is very useful for many things."
