Weedeater

"Weedeater" became a herbalist at 1yr old, a successor to Lennon who knew that his apprentices young mind should be started as soon as possible
He had an actual name but it was lost to time. He was dubbed "weedeater" by the elders soon after he was an adult and it stuck
Strangely "weedeater" doesn't seem to talk but he and his sister seem to understand each other just fine
He has an obsession with plants. when he isn't busy he just stares at them for hours
