Well my memory must have forgotten about Baal. Which big event are we talking about?. I totally recognized his name.....
He was the Archon of Caerwyn who betrayed/declared war on Astrum and led the "League of Free Nations" (Caerwyn, Averoth, the Saxons, and some elements of Madina/Aurvandil) in a war to destroy SA. Basically responsible for the whole Caerwyn Crusade, the pillaging of most of southern Astrum and (at least indirectly) the death of Vasilif Rowan of Astrum.
But in the big picture to Khari Baal was Rynns guest and elder of his faith. She needed to allow it to happen. VE should also not like Khari so much as she closed a magnificent temple in Farrowfield long ago when Kabrinskia was formed.
I guessed as much and it makes sense, although of all the VE Elders Baal was probably the worst one Rynn could have invited. That said, its unlikely anything will come of it now that the wedding is over and apparently everyone who was there forgot who he was.
