[Sandman]

Some generic theme ideas;

Hostile Forests: The growth scale is inverted for the purposes of calculating eney supplies. In other words, a strong growth dominion will cause enemies to starve like a strong death dominion, a bit like Mirkwood in the Hobbit. Carrion Woods should have this ability as standard.

Warrior Cult: All frienly units in your dominion gain experience faster. You also start with an Academy of War in your capital.

Mercenary Kingdom: All mercenaries cost 25% less to hire. Mercenaries will join your cause permanently if you hire them for nine turns in a row. This theme allows access to some special mercenary bands, and also has a chance of attracting unique mercenary heroes.

Engineering Feats: All fortresses under this dominion have a defensive bonus, as well as a look-out tower (better patrolling) and escape tunnel (units can leave or enter a beseiged fortress from neighbouring provinces).
