Mayor's Assistant

[De_Geus]

The mayors assistant will look after the city.
He/She can be configured to replace wheat fields and wells when they are exhausted.
He\She can also send out geologists when mines are exhausted.
The mayors Assistant can be recruited from the Gem shop and would cost 100 Gems per week.
It would be stackable so you could buy him/her for 10 weeks if you wanted.

Many other games like O-game and Lord of Ultima have these kind of assistants.

nice idea- usefull for holidays- now if only he would also sell off excess materials ) But i guess that would make it too good to be true

Another option could be having Sitters as in Travian.
