During their long journey lazarus and Aidan had traveled with prince Albrecht to Tal'Rasha tomb and found a mysterious note on the ground ... "If you can even purify ZorunTsin and combine his skull with a Sha'Ad stone... you might get an unknown void chest emitting an unknown aura of dark power",
In the meantime they did follow the note and then once they opened the chest:
They did split all their worthy items, so leoric bought a new castle in a rebuilt tristram with his wife, lazarus bought a new chirch, albrecht some shirt, and Lachdanan a new armor !
What a great story in sanctuary
