So I noticed something interesting going back, and rereading, Asgeir's journal "A Burden", and how it possibly relates to the Icebrood Saga story, and Braham.
If we read "A Burden", and look at the other lore behind Asgeir's fight with Jormag, Asgeir lost to Jormag because
When it comes to Braham, we have already been told by the Spirits of the Wild that Braham is now part of a prophecy, and that either Braham must kill Jormag, or Jormag will kill him. Braham has also mimicked several of Asgeir's actions, both by getting a weapon infused with Jotun fire magic, as Asgeir had, and by getting the Spirits of the Wild to channel their energies through him to slay one of Jormag's champions(Drakkar) as Asgeir did Frostfang.
Looking back on episodes 1 and 2
I suspect that in episode 5 and 6 we will meet with Bear and Snow Leopard. Bear will make us do something that requires us to keep pushing through the pain and exhaustion to keep fighting, and Snow Leopard will have us do something that encourages us to use non-direct tactics against Jormag, as fits with those two spirits ascribed elements.
Essentially, the Spirits are teaching the Commander and Braham how not to fail in the inevitable fight against Jormag as Asgeir did. Getting the bow back, and Braham being able to channel the Spirit's powers, will be key in defeating Jormag, as well as the lessons learned here.
