Excalibur's End

On the East coast of Elysium is an ancient sword embedded in stone, the Yutto's think it may answer some of your questions

Here is a list of NPC's you will speak to throughout the quest

One Who Has Taken Vow of Truth
The Melting Pot, Elysium (720x1550)

Speak to One Who Has Taken Vow of Truth, he can be found under one of the tents at the Yutto's village just southeast of Ripwell (Clan) or south of The Jagged Coast (Omni). Talk to him about the past, he will suggest you have a trip out to see Excalibur's End

To get there you will need to head East from Ripwell, at the Shere statue turn Northeast and carry on till you reach the water. Excalibur's End is on the island just across the water, there is an old unused portal there. Be careful of the Heckler's and Crippler's in this area
