Before we came into this flashback we learned that mana was being poured into Kunabula from an unknown source. We learned that both Sol and Lorkan has mana inside Brian. Lorkan is trying to kill Sol and Brian’s contract THEN kill Brian so they are not tethered together. This will cause them to disconnect in the next lives and not be able to find or remember each other next life onwards.
So, my question is, is the mana problem in present Kunabula possibly Brian/Ian related? I ask because maybe the contract between Sol and Brian really did break or severely weaken in Ian. Maybe the difference in Sol’s mana that was in Brian is now out of control in the present circling in Kunabula because energy cannot be created nor destroyed. I think Brian’s mana just sat there for 900 years. And since Ian was born and growing up, in turn reacted to his rebirth and wants to return to Ian so it’s acting up. Maybe Brian’s mama has a left over will and longing to reconnect to Sol through Ian.
