Fifteen hundred mercenaries, mostly in rank B, about one hundred in A-rank, and six S-rank, not counting Theodore, who despite being an S-rank, has really high combat experience almost equivalent to Cassidy's before train with Lucien.
That is the strength of Theodore's mercenary group, which, although not as incredible as Scarlett's mercenary group, is a considerable force, and that could conquer the cat-clan after Mirya, the cat-matriarch, take part of her elite warriors with Eve.
But of course, Eve would not leave the clan more fragile and made mainly of women, unprotected. So, she left a considerable troop of elves near Oxard at Nina's orders.
However, these troops won't be necessary…
"Don't you really want to go with us? There's nothing like adrenaline in a raid." Theodore asks Bowen after his twenty ships are ready to sail.
