Why is the Princep's Memorum on the west side of the Garrison? If the Marat showed up in FOC wouldn't it be more to the east? I doubt that the Marat could of crossed the Garrison and all those steadholts unnoticed without attacking anyone or being seen. I Always thought the Garrison would be to the west and the steadholts were on its eastern side.
If you put the steadholts to the east they would be totally unprotected which wouldn't make much sense, would it ?
The Marat who entered the valley came in a small group, through the mountains. They never went anywhere near Garrison.
The Crown legion fought the Marat after/while they overran Garrison and the valley, so the position of the Memorium is quite alright.
On a loosely related note.
What strikes me as odd is the fact that Kordholt (later Aricholt) is so far from Garados. They used it as base to hunt the Vord on Garados... makes no sense for it to be so far away.
But like I said before, the whole of Calderon deviates from how I pictured it myself.
I bet Jim did this on purpose... he wants to confuse us. :-)
