CWK weapons mystery, where is the end of storyline?

I think that there are definitely some missing facts here, but it seems like they did make it, just forgot to implement it. Like somewhere there should be a description of how the Crimson Guardians broke down the lightning shield, but we do know they had something to do with it.

Surely, there are. Who knows, maybe they will implement the other quests later? Something like Ellin Forest, which doesn't have any quest currently, but could get some in the future..

Also, do you think there will be more quests with Raven Ninjas?

I hope so. There weren't many quests with them. What about Lukan? Everyone forgot about him, too. He got transported from the past to the time period we are now, and he just remember seeing a big light, then nothing. Then, he found himself in the time period we are now.

Many things yet have to be explained, don't they?
