The low mana level in caithness is of course why megalos hasnīt overrun them yet, there legions rely heavy on battlemages and attached wizard corps.
By the way here is a discussion on discord I started when musing on what would happen if a larger modern army would clash with a magically supported Yrth army aka megalan legion, which is in defence and had time to prepare. I wanted an open battle so I stacked the cards and didnīt took mind spells into account, the idea needs a lot of fintunin though but may still be worth a read for the differend standpoints. I was mostly on the fly because I lost my old notes about it which included several math examples and the possible outcome of certain other spells. I still thought i had my notes when I started it. Save early save often, but what do you do if your USB sticks got lost?
