Slow progress

I've been distracted recently and haven't done much. I've added a large number of unit types, though, as well as a few minor features.

New Units:

I've added two new mage upgrades, the cleric and necromancer. The cleric heals units in its province each month by 20%, and the necromancer converts units it kills into friendly skeletons which disappear at the end of the battle. Upgrading the necromancer allows for the creation of permanent undead.  (Still unsure whether to remain these units to white mage and black mage, to keep the red/blue mage theme.)

I also changed how infantry units are upgraded. Now, only spearman can be recruited. Spearman advance to powerful swordsmen, highly armoured pikemen, or armour-crushing macemen.

Lastly, I finished up pretty much all of the upgrade trees.

Heroes

Certain feats will allow a unit to become a hero. Heroes can recruit new units, like leaders, and, if the leader dies, a random hero replaces them. Heroes also gain a title appended to their name.

Dragon Lairs

A very minor feature: each world has a few dragon lairs, provinces that contain only a ludicrously powerful dragon unit. Defeating it confers hero status to the slayer and offers a large gold reward.
