Wodenna

 is a fey woman of terrible reputation that, according to the Archfey Artagan, had a relationship with him in the past. As an NPC, is played by Matthew Mercer.

Appearance
Wodenna wasn't fully seen on stream, but she is reasonably tall, with a crooked hand of very long fingers with hooked nails.

Personality
According to Artagan, she's a terrible woman, and somewhat scary, even for him.

Background
At some point in the past Wodenna used a tree trunk to make herself a home, creating a visually welcome interior inside the rough looking structure.

She allegedly had a relationship with Artagan, which ended on bad terms.

When Garmelie agreed to help Vox Machina travelling through the Feywild he warned them about several places, including the Hut of Wodenna.

Vox Machina passed near the Hut of Wodenna, and Scanlan and Pike decided to inspect flying with Vex's broom. Through a window they saw a nice interior, and Wodenna sitting on a big chair with a tea set in front of her; when they got a glimpse of her scary hands they tried to flee, and the broom briefly lost its flying capabilities, recovering them when they were far away from the hut.

While being interrogated by Vox Machina, Artagan asked them if they avoided the hut of Wodenna, admitting his former relationship with her and stating that she wasn't a hag.

Trivia

 * Wodenna appears to have some magical influence on the terrain surrounding her hut, being able to detect the presence of spies and deprive their flying broom of its abilities.
 * A possible explanation for it would be that she's some sort of Archfey, capable of manipulating her part of the Feywild; or a fey old enough to establish that control even without the Archfey status.
 * While it was confirmed that she was not a hag, she presented many of the characteristics hags have in the stories, including a bad reputation, a monstrous look to her appearance (her hands), and a seemingly welcoming home with enticing scents.
