Indiriki Perdan beaten by Sirion to a pulp. Ha I laugh at that Sirion are isolationist they like their side of the river to much. Beyond those choke points they are not so great.
The same could be said of Perdan attacking Sirion. We tried for years, and never could get past their border, with the exception of one or two northern raids that didn't do much.
They couldn't save Caligus let alone truly threaten Perdan.
Of course not. The geography is all wrong.
