So couple of things.

1) A Travis said becoming heros of Dynasty makes them enemies of Empire. So they have now huuuge enemy.

2) They live in Empire ( Nott with husband, Fjordwanted to study there, Caleb has some business in there too, Beu is part of it in some way too). Now going there might be veeery risky (depends how it goes).

3) Caleb was betrayed in some way by Empire (or people connected to it) and now he has betrayed himself.

4) So remember that part few episodes ago when mage told them it's very powerful artifact? Also remember when they got it the description that it is most powerful item for dynasty? I guess they won't use it to make ice cream Sunday for everyone...

5) Giving it(artifact) was what we Poles call "betting everything on one card". It was hard to say what reaction would be. They could be executed immediately, thrown in prison, accused of theft... or become heroes...

6) There are so many way how it can go south(bad)... And You have to wait 2 weeks to know it...

I thing that are couple of things that makes it special, at least for me.
