Black Court
We can cross out the white council reinforcements. They always arrive late. All they can do is to wash the floor, so I suspect we won't be seeing Luccio in battleground.
I got a strong feeling that Mavra will be making an appearance and it is likely that Ebenezar will be facing Mavra head to head.
Analysing the top combat power of both sides:
Ethniu from the soggy bottom team has no counterpart. No equivalent power to restraint her. So I suspect Harry , the KoTC, Murphy and co will the the one to handle her. Only the plot armor and the protagonist Halo has a chance under such a overwhelming disadvantage. May the Almighty help them.
Either Mab herself or the Leanansidhe will be on the Chicago team side which is balance by King Cord on the other team. She already prepared in the case she is needed at 2 places at the same time. This time her preparation pay off.
Farofax is out of the game. He said it himself, a dragon cannot fight without destroying the city of Chicago in the process. Vadderung could probably play, though I suspect someone in team soggy bottom will restrain him as well.
EB v.s Mavra.
LTW, Martha and Christos will probably end up facing Cowl and the black council. Well, assuming Chistos is not black council himself.
Leaving Molly, Ramirez and the rest of Marcone and Monac's forces against the fomorian army.
I doubt the mortal police will play any role, except for some character like Rudolph and his partner. What his name again?
If Ivy take the field, team Chicago may have the advantage. But Ivy is neutral so she probably won't shoot. Well unless the Denarians come out to play, in which case Ivy has a reason to take action. Ivy and the Denarians has a score to settle.
