Okay, so now that I've given these sets a closer look, I must say this is a pretty good line, if I was still a kid I would probably love it and get every set and follow the story. At least I think so.
The mix of medieval weapons and martial skills with high-tech vehicles that was successful in Ninjago is used again which is cool. The new weapons can be good for Scifi too as powerblades / staffs.
From my point of view, fig-wise we get generally good-looking lizardmen, werewolves and Avians, so more options for creating a Fantasy realm with various races. Only downside are the lions (kinda) and the fact some of these parts might not be as easy to repurpose as you might like.
The bad eagles are pretty much a godsend for the way I'm trying to make High Elves (they're supposed to have a bit of an Aztec look going on), look out for the chick with the wings (high elf priestess), with some minor adjustments those eagle guys would fit right in with her:
Many of the models are totally Brikwars. Just look at that thing:
Giant lion-head on big wheels with large cannons on each side. Yes!
The line is very vehicle-based to say the least and some of these vehicles are a bit chunky, but you get a lot of useful parts for building your own vehicles, in many different colours, as well, if you buy sets from this line.
