I am really fond of handing out player aids during the games. One of my favorites of course is a map. In the previous campaign I ran, the PCs at one point had to explore the regions across the big central mountain range on Ruarc. They of course didn't have a map.
This was remedied when they met their NPC Guide named Hjalmir. He had a map that he had put together based on his journeys - this is that map.
This was done entirely in photoshop.
