IG messages beg to differ. When D'hara defeated the one or two Solarian nobles that attacked Sallowwild they boasted of the victory far and wide. Stop and listen everytime D'hara wins a battle. It doesn't happen often but just listen.
Also if LN's performance was pathetic, what does that make D'hara's? I remember this realm they sent military aid to, Luria Vesperi. What happened to them?
Luria Vesperi was too busy ordering suicide charges in waves and hoarding gold for defeat tournaments to be properly defended.
