Thamas I Barde (IPA: /ˈθæməs baːd/), also called Thamas Gensattonha (Thamas, the Death of Nations) was king of Lokren from 73 AD until his death in 98 AD. He is most well-known for defeating the Red Ribbon Rebellion, which plagued half of his reign, and the slaughter of the Ardryn prisoners who had surrendered to him at the rebellion's end, from which act he gained his epithet of Gensattonha. He was succeeded by his son, Alcherth I.
