I have been drawing this over the last week for a game tomorrow and it is finally done. Here are two versions, with more/less colour intensity.
The WIP thread is here.
This is a map that will be used with maptool. The party has found the location of a hidden camp of pirates and bandits. The pirates are holed up for a few weeks conducting repairs on their ship. This close proximity with the bandits has inflamed tensions between the groups that only tolerate each other normally. In addition, monsters have moved into the treasure cave, further exacerbating the situation. The party arrives into the middle of this. If the blunder in swinging swords, the two groups will unit against the common enemy. If they play it more subtly they have a chance to play the two groups off against each other and significantly reduce their odds. Should be interesting to see how the game goes.
