Alpha access is kinda expensive, but there will be open beta i.e. free tests, scheduled just before soft launch "next summer" and requiring only registration on the site. Here is some more early test footage - cartoony looks should enable smooth battles with hundreds of players, collision detection, physics and destruction.
For quick intro & lore, say - it's IGN Wiki, Pantheon (gods) and Archetypes (classes). Here is an Imgur album with hundreds of images and screenshots. Say, a pic of what happens to normal cat (in spring) in the end of Campaign (winter):
Very important thing is - player's identity is tied to the crow-spirit and NOT the body - this will include frequent changes of class, race and sex!? In other words, once you die you'll have to fly and find a new corpse, unless you got friends and/or spare one nearby.
This, same as Crowfall's progression system, resembles Eve: spirit/body parallels pilot/ship, and bodies can be crafted (or even stolen/looted on some servers) through necromancy skill - in qualities from white/green to epic or legendary, to use WoW terms:
To tell a story of that comic: at first (pages 4,5) a knight chooses to serve Malekai, the Lord of Shadows, one of 13 gods. God grants him eternal life and other specific benefits, but the knight is obliged to fight and pillage in Malekai's name - this might include building and maintaining god's statues and temples (which also cost gold and resources for taxes and maintenance).
After that (pages 1,2,3), on the 47th day of the War of the False Kings, the knight dies and the crow-spirit leaves to fly and find another body (pages 6,7). On the graveyard nearby, the crow finds the corpse of fallen champion, possesses it and walks away to fight for Malekai again.
...and they all lived happily ever after :D
