Ruin Explorers Fam & Ihrie

Fam and Ihrie are two Ruin Explorers, trying to make a living by salvaging old relics hidden in the ruins of a long lost era when magic ruled the world. Although Ihrie is a powerful sorceress, she has been cursed and everytime she casts a spell she turns into a fluffy little rodent. In order to remove the curse she is looking for the Ultimate Power that is sealed by three relics they must find. However, Ihrie soon finds out they are not the only ones who desire this power and while some of the competitors may be friendly, others seek this power to spread evil across the land.
