As a very special Thank You to the fine people of Bay12 who absolutely gave us the critical boost we needed in the early days of the Kickstarter (as did RPGCodex) we would like to let you describe/design a terrifying or enlightening Fallen Primal that wanders a shattered landscape in the "What Gods We've Made" supplemental scenario. This creature will function similar to a Lesser Evil in that it can be persuaded to help you, work with your enemies, or simply be bartered with to gain access to its unique powers. In addition, the Fallen Primals in this scenario have campaigns associated with them to enact very powerful effects, either one-time or recurring.
One of the current Fallen Primals:
The Fallen Primal of Hope
Image: Corpse-like giant moth shining a weak light over a swamp
Power: Can restore otherwise fatal wounds
Campaign Effect : Heroes Overwhelming Victory - Empowers the Primal to assist the Alliance, greatly increases morale and can lower corruption over time. Agent Overwhelming Victory - Spreads corruption passively and is now now drawn towards high morale areas.
Essentially we'll want a concept, a general idea of how it looks, and some kind of effect. The Primals can also have physical presences and be available as Minions, Elite Units, or Global Threats.
There's not really a way to vote here, but I don't want to take it into our forums to punish any non-backers so we'll just see if people can generally agree on a good idea.
I also have included an Event referencing Bay12, and there's more than a few Dwarf Fortress references (mostly in Ruins).
