I would suggest making minor changes to the way the teleporters in the white stone map operate to make travel over this huge map easier. I propose that the teleporters should work in a square pattern, rather than the current diagnal pattern.
For instance the teleporter closest to Lakeside should teleport you to the teleporter near Vermer Castle. The Vermor teleporter transports to WSC teleporter, WSC teleporter transports to Grahms and so on.
