Between Life and Death

Skeletons in the Vengeful Spirit's Basin are getting restless. It all started when you brought back Zian's Proof.

So I searched some records and found out Zian Manas was related to Delfaras' famous Mercenary Commander Victor, and after Zian retrieved the proof, Victor attacked Zian to steal it. He ultimately failed and ended up dying with all his troops.
When the Black Siła of Northern Land spread across the continent, Victor was reborn as a Skeleton Commander. So this is a sign that the Vengeful Spirit reacted to the proof.

While I was reading these documents, something came to mind. I have a task for you. Find the <HFFFA7272>Yellow Magic Jewel<HFFFFFFFF> among the remains of the <HFFFA7272>Haunted Inn<HFFFFFFFF>. It will be useful.

I heard Skeletons are coming out of the Vengeful Basin. Are you going to wait for them to attack this city? Quick, find the <HFFFA7272>Yellow Magic Jewel<HFFFFFFFF> from among the remains of the <HFFFA7272>Haunted Inn<HFFFFFFFF>.

The Yellow Magic Jewel was extracted from the skull of a corpse. It was used to erase all memories the dead had of this world and blocked them from approaching. If you have this, I think you can erase the memory of the proof as well.
