How does the Gardening Goblin show up in your house with memories of it? Also, why do the Droags keep suiciding legions of themselves in an attempt to destroy Ganak's Battlement when they can just fly over it and bomb the defenseless harbor to their hearts content?
i would presume that the memory spell was broken sometime during the adventure line while you are doing the TS line, the whole purpose of the ts line at the start is looking for the people doing the adventurer line so it's possible while doing the TS line the adventurers reveal the chaos stone's location and lanys breaks the memory spell in the region.(near the end of the adv line you reveal the stone's location to the goddess of nightmares, lanys appears takes the stone, casts a spell and says "This land... It is shrouded by magic, no longer!") as for the battlement, withered lands has shown that there are anti-flying magic that will make you fall to your death and in cobalt scar (TS line?) it touches apon the idea of an air shield, they may be able to fly around it but that's not the same as securing their line of advance. attack by sea would mean they run into danak docks, bypassing the wall and landing in the plain between the docks and the battlement would leave them surrounded during battle and the possibility in trying to flee would get too many droags killed. this is before you factor in supply lines and the efficiency of transporting supplies, it's far more effecient to move supplies by road for an army then to have each trooper be responsible for transporting his own food.
Reminds me of a D&D adventure decades ago.... the confusion spell 'cast' by a mayor (read politician) was MORE effective against characters with high intelligence, because they'd were 'hey, wait, that doesn't make SENSE'....
Regarding the "forget me" spell on Obulus Frontier, that was actually broken by the bad guys at the end of the adventure line. All bets are off now...
