I was wanting to call opfaal for something else but wanted to work on your request as well.
I was lead to draw the sigil on a piece of river birch bark I obtained recently.
Birch is associated with the rune Berkano
Opfaal accepted the charge(s) but I gotta feeling like there’s more going on, and your situation may be a bit complicated (or at least that you’ve got other things in the mix) but I couldn’t get a clear read about it.
It was requested that I add my Channeled rune sigil/stave to the equation, and I obliged. (Likely related to the other parts of your situation)
With that, it is done.
