Currently strongest TC army I see is in 86 (previously my castle). Its 400 strong. with dozens of mages and his pretender.
He has TC, Abysia, Ermor and Jotun capitals. He has many forts. He has strong armies in 116, 83, 27, 40, 20 (Yes, that's my capital - he always has more armies to throw at it

)
Actually with some buff spells I could make him pay much steeper price for the castles he takes from me but lack of Earth, Nature and Death gems prevents me from that.
@Bwaha, maybe you could actively help us by gating a few SCs to a safe spot in TC turf, then build a lab there and start GWing huge armies. With your help we could indeed bring TC down fast.
