Malga Mine is a mine located to the north-west of Rolent. It is where Rolent gets most of its sepith from, to use as export goods.
In S.1202, a large piece of septium ore was discovered. In one of their jobs for Cassius, Estelle and Joshua had to go there to retrieve it and then give to Mayor Klaus. While they were there, there was a cave-in and a den of monsters was revealed. Estelle and Joshua worked fast to rescue the workers and managed to make their escape. They then gave the Sepith Ore to the mayor for safe keeping. It is later revealed that Kyle Capua was responsible for the cave-in.
Later on, the Sepith Ore was stolen, but it was retrieved.The sepith ore was then refined and decorated, and gifted to Queen Alicia von Auslese for her birthday as a present from the people of Rolent.
The Mine Chief later revealed to Estelle that the hole has since been blocked up.
