Return to the Crowfather | The Lord of the Black Stone Darksiders 2 Guide

Before leaving this place, don't forget to look inside the chest. It will appear in Samael's previous spot. Afterwards, open the world map and select the [Tree of Death] (you don't have to go back to the present). There, talk to the Crowfather to finish the mission (rewards are: 2500 XP and 11000 gold) and unlock the final main quest [The Well of Souls].

[TIP: According to the Crowfather's warning, entering the Well of Souls begins the final main quest of the game and it's a road of no return. Therefore, it's a good idea to stock up on supplies and complete all other side quests (the game will allow you to complete them after defeating the final boss as well, but only if you agree to return to the last checkpoint right before the final stage.)]
