Guilds of Cadwallon has added a game board to their Kickstarter campaign. Go take a look.
From the announcement:
If you’d like a traditional board, here’s something that will fit 3×3, 4×4 or 5×5 grid games, with an overhead view of the city of Cadwallon printed on it! Ideal for use with all the unlocked additional cards and Agent Pawns! Please add $5 for shipping outside the USA.
