Lyrium

Lyrium is a valuable but dangerous substance that can grant magical powers to those who consume it. It is a highly potent liquid that has been infused with trace amounts of Dragonstone dust. Lyrium is primarily used for ingestion, but it is also used in some places to enchant items or to perform rituals. In rare cases, it can also used in tattooing or in the crafting of runestones.

Lyrium consumption is believed to open an individual's mind and body to raw, unpredictable magical capabilities; it is also known to be highly addictive.
