Personally, the only way I see somthing like this working, is if these quests are randomly generated. But, thats not to say that there couldn't be pre-created quest 'themes' and flavor/desription text. But personally I belive examples are best given:
Your soverign gets a quest. the Quest is randomly titled:
WAR-DUCKS
This is based upon a pre-scripted theme. This theme could be entirely random, or based upon current events within your kingdom. In this case, its random. The theme is 'War Animals' (for humorus effect).
War- is a preset prefix for the quest. Then a random animal is taken from a database. In this case ducks. Perhapse a tag is attached to this, for reward, and quest reasons.
* will indicate that this is determined by the chosen animal, or its elemtal tag.
** indicates a random variable, perhapse depentant on the turn, or level of your soverign
The Quest description reads:
***A Strange magic is corrupting the *ducks of the nearby land! You must save us, or the *ducks will destroy all we have worked so hard for! Defeat all the nearby *ducks within *2 turns.
***This text also could be a variant of 2-3 different options, or not.
The result:
**4 *Ducks appear nearby. They are reasonably powerful.
This is perhapse dependant, again, on either totally random variables, or ones that are influenced by soverign level or other factors.
You defeat the Ducks, and return for you reward.
The result:
You gain **400 gold. (and probably some other, generic reward.)
And maybe some kind of reseach or magic bonus in water (or whatever the closest one is), because the animal was a duck, and it had a water (or equivilant tag) on it.
Just an idea.
