Lego Olympus is a invented theme about old greek myths.
I think its good to have a theme like this, because the stories are good to base sets on that you can play with.
The myths are also very interesting.
Every set comes with a little comic (like in Lego studios and Orient Expedition), where children can learn about the myth of the set.
Some possible sets are:
minifigures: Theseus, Daedalus, Icarus, Ariadne, the Minotaur, King Minos, a scared boy and a skeleton.
includes: The labyrinth, the palace of king Minos and some wings for Daedalus and Icarus.
includes: Pegasus, the Chimera and a cave where Bellerophon can keep his weapons in.
I'l make more sets soon. If you don't want a whole theme but just one set, support one of them.
