Christian was nice enough to send me some hexmap templates, and last night I had to take this one out for a spin. This is hex 14-t of the Langrim map, and it shows the area surrounding the Ruins of Dwergard. The map is 25 miles across, with each hex measuring 2.5 miles. The biggest problem I ran into was how to list my coordinates, and the way I ended up doing it doesn't strike me as ideal, but it'll work for now.
The following is the background information on the Ruins of Dwergard:
The dwarves of the Järnafíorin clan came to Langrim from their distant homeland, some time before the Isolation. They had charters from the Emperor giving them exclusive rights to mine the mountains on the main island. A cold winter, some one hundred years after the last ship, a goblin surge washed over the land, leaving farms and villages in ruins. The people fled behind the walls of the larger towns, and after a hard winter with many battles fought, the remaining goblins withdrew from the surface.
No one ever saw the dwarves of Järnafíorin again after the Goblinwinter of 107. Their last stand has become a fixture in the island's folklore, and the ruins of their stronghold the target of many an adventure. Some of those who seek it out return with pieces of the fabled Hoard of the Dwarves, but many others never come back. The hills and mountains around Dwergard is infested with goblins and monsters, and the dwarven keep and mines are said to be littered with traps and ancient war machines, and haunted by the ghosts of the dwarves who fell there.
The GM's map, as well as some dungeons and encounter tables, are in the works. These will be posted at a later date, dependant on campaign progression.
