I made this model for sculpt january 2022, its based on an illustration from the wiki of ice and fire.
It is probable that Greenbeard is a deserter from the War of the Five Kings.
Arya Stark meets Greenbeard when he visits the Inn of the Kneeling Man. He is among the members of the brotherhood that escort Arya to see Lord Beric Dondarrion, rather than to Riverrun as she desires. He speaks with Lady Ravella Smallwood at Acorn Hall and with the ghost at High Heart.
This is a decimated version of a model sculpted in nomad and zbrush.
