Germite is some kind of mineral that forms crystals. It emits toxic fumes that are said to challenge the strength of the mind. Those who succumb to it are shown visions, or delusions, only those strong enough to overcome it are able to survive.
Another property of the crystal is through magic it can keep someone alive.
