My group and I are doing a Champaign that is Set in Mordheim, and I crafted my own objectives to match the setting. So far we are in play testing. Right now we have a couple of names, Mordhiem Burning, Mordheim Aftermath, and Mordheim Ever After are all the names we have.
There are 4 settings,
New Mordhiem the part of the city that wasn't destroyed or effected by the commet,
Ruins of Mordhiem the old feral city that has been warped by the commet,
On the River - Beach and Water setting and the life on the RIver that runs through Moredheim.
The Wild the Rual Area Surrounding the City.
I have 7 objectives, some of them I think are better than others.
The Warpstone belongs to Us - Skaven, they are collecting Wyrd Stone Shards and refining them into Warpstone to take back with them to power Skaven Machines back home. Think Skaven meets Lure of Fortune
Kill and Bring Back an Army - Undead, the warband gaines bonus Zombies, and there is a bonus that allows zombies to gain exp at half the rate of a normal person like the Man Eater Flaw. Think growing a horde of Zombies and then attacking the city.
Road to Hell - Chaos and Undead it is all about opening-up the hole to the other world and bring chaos into Mordheim. It is all about Mutations, Opening a Portal to Hell and Demons.
City Guard - Human Mercs, High Elves, you know the good guys. It's all about restoring order to the city and capturing the 4 towers of Mordheim. Think City Watch meets Celestial Protactorate.
Protecters of the Wild - Lizardmen, Amazons, and Wood Elves - it is all about killing anything evil or chaotic that wanders into the woods, and making raids into the city to hit strategic targets. Think the Alt-The Damned Shall Burn, but with bonuses that give individual models bonuses.
Treasure Hunters - Human Mercs, Dark Elf, Dwarves, a few others It is all about collecting magic items, and trying to find lost items in the city of Mordheim
A Pirate's Life for Me - All of the Sea Fairing Races - It is all about getting together items like a captian's hat, a Jolly Roger, Guns, Swords, a Compass, a crew and a boat to start a new life as pirates.
Right now we are really in play testing, but so far everyone seems to like the concepts. I think everyone likes the Idea that we can play the different setting and they would have slightly different rules, and would allow different adventures.
