Ok, maybe this would mean you sent 2000 mages more or less.
Still an elf with 2000 mages at 30k ks, seems a bit excessive. It's possible but excessive.
This is a simplistic analysis but this is what leads me to think you had that many mages, which would be unsustainable at this stage. Maybe I'm wrong but this is my crude analysis. Forgive me if I'm wrong.
