Sǫlrún

Chaotic tomboy gremlin girl. Einarr's childhood friend.

Though she recognizes the importance of her sailmaking job, she always dreamt of joining the guys on their viking voyages as a badass shieldmaiden, maybe dying on the battlefields, becoming a valkyrie of valhalla...
Overall, she's a fighter, she wants to battle. She's not someone who conforms to gender roles, she does not like to stay inside to make food and weave fabrics... she wants to do the heavier work! She wants to raid! Pillage! Cause chaos! Be a viking! Go feral! Yes!! At least, that's her impression of what it probably was like based on the stories she heard from the returning folks. 

But yeah, Sǫlrún was definitely still a cis girl, no matter how much she wanted to do all the manly activities. See, she wanted to do them, but specifically as a girl. And even if she'd adopt a boy name and wear boy clothes to be allowed to do the boy activities, she'd still like to return to being a girl. This confused young Einarr greatly, and probably contributed to his realization. 

Besides that, they did do activities such as roleplaying together. Live action roleplay, perhaps. Obviously they didn't call it that, but that's basically what it was.
