Miners In the Sand
To make this quest available, first complete the mission "Fae at the Mine".
Apule Vire from Motus Mining Outpost will ask you to talk to Fae named Calovar. Apule suspects that he cursed miners. You can find him in the central part of the location M3(10).
He will tell you that the real cause of problems of miners is Edgar Aron, who hides now in Aron Excavations Mine M3(12). You have to take back from him a magical artifact.
After short conversation you'll be attacked by a group of beasts. Defeat them and then decide about life of Edgar. Regardless of your choice, you'll get Calovar's Relic. But before you kill the man, complete the task "Bloodbane". After Edgar's death you wouldn't be able to do this.
With use of Calovar's Relic you can heal a group of mad miners M3(14). Approach each of them and use a stone.
When all miners are healthy, collect your reward from Apule.
You will finish this mission giving back artifact to Calovar.
This task will appear after completing the mission "Miners In the Sand". You'll become then an owner of Aron's mine, which is located in the northern part of Hollowlands M3(12).
Visit the mine and the office and then talk to two workers. You can collect money from Vincent Helvern and order him office upgrades. To complete this task, you have to upgrade the office three times, spending for that about 10,000 coins.
Bon Anjar is responsible for developing the mine. "Buy" three upgrades and you'll finish the mission. The mine will be enlarged and you'll find there some new treasures.
Once you're inside Motus Mining Outpost, meet a man named Odvar, who will inform you about a reward for killing Crudok - Bloodbane.
In order to find him, you have first talk to Edgar Aron, who can be found in front of Aron Excavations Mine M3(12). He will tell you about group called Brownies, which always accompanies Crudok. When you kill smaller enemies, their leader should appear.
You can find beasts to the south-east M3(13).
After defeating Crudok, return to Capstan to collect your reward.
