Hello all, I am one of those new players. I have a question. I am playing the undead faction. I know they don't grow their population food. I am stumped by a few things. I have built cleric add-ons to my city that should increase my fame (if I am remembering correctly). Thing is my fame seems to be stuck and not increasing per season. The only time it increases is when I discover something or do something heroic. Issue #2: Is there a limit to the number of heroes you can have? I currenly have 4 (wondering if that is why my fame is not going up with the cleric houses anymore). #3: Is there a work around or someway to group your army? Everytime my army comes to rest on a city tile I have to single click on each member to bring it out again.
Thanks!
About undeads, building consulates to the outposts will help. Especially in towns that's faraway from action where you kill people and convert them to skeletons. The most I've ever done is attach five consulates to a single fortress to get onyx throne really fast 
Morrigan's Call gives +1 growth for each death shard you control so if you have ten, you have +10 growth in cities with essence slots in them.
And then there's the last way, kill humanoids and they will be brought to your nearest cities and converted into population aka skeletons. This method is most unreliable but can give massive growth in short space of time. And, if you slay a human army, any monsters in it like wolf will count as population even when they're not human lolz.
Undeads is very slowpaced faction.
