I have added mana nodes, which can bound by a wizard, giving additional mana each turn. To bind them, order the wizard to travel to the node, and then next turn you can bind it. Currently, there are never any guardians, and all nodes are the same size. Also, I will be adding some events related to the nodes, such as the magical energies seeping into the water mutating the local populace, nodes collapsing or growing, etc.
Save game has had a number of crashbugs fixed, so it is functional again. There are a few bugs with games loaded from a save game, some stuff can disappear and fog of war acts weirdly after loading a game.
Behind the scenes I have been adding support for artifacts, since I needed those for the warlock events/quests. These are powerful objects which can be used to cast spells, spread blight, open portals to other planes, dominate monsters, etc. I am also working on a spell which turns slaves into Mongrel Men for use as soldiers.
