Greetings fellow kings and queens and knights and bandits and trolls,

For those dedicated few who had defeated the troll king and gotten the ginormous red gem, does it do anything? How about the troll cave? Does it give anything other than coins?

Trying to decide whether to use my wisp lanterns to expand my kingdom, and enjoy a vacation or three in the dark cave tour with the wisps, or to use them all up in the troll expansion.

All my buildings are squished together right now; I have to store some of my royal buildings to place my workshop etc. It's becoming a bit of a pain. Like to do the low cost expansion soon, but the troll is beckoning. Should I get him urgently? Is there any tactical advantage? Or can he wait?
