I have been a member of this exploration team for many years.
The Oblivion Border is dangerous, but it's also brimming with tempting treasures.
The Psirens in the southwest have riches, too, including some incredibly precious gems. The Sorrowful Sea Sirens have Psiren's Tear, and the Screaming Sea Siren have Psiren's Lament.
If you can get these two gems for me, I will pay you a high price.
Not many people know that sea monsters carry gems. It took years of studying historical documents for me to come to that conclusion.
Legend has it that sea monsters summoned by Psiren will become Screaming Sea Sirens, and sea monsters touched with Psiren's Tear will become Sorrowful Sea Sirens.
