Glaive was Glaive, unpredictable keeper of Henir's Time and Space. But Glaive was also bored… So he just decided to mess with time and space some more than usual.
Which resulted in, more or less, crossover.
I support theory about Helen being a demon (with actual knowledge that she isn't).
So, yeah. Me and my boyfriend like both Nanatsu no Taizai and Elsword. NA Elsowrd GM's like Elsword and NnT too. My boyfriend have good contact with them. So they had a talk, about crossover between NnT and Elsword. And they came to very interesting conclusion.
This conclusion is, Elsword main team power level in 1:1 scale. And it presents itself at least interesting. Pretty high, actually. I'm not going to share the secret right now, but few stories should put some light on it.
You may guess, you may bet. Let's see who'll be closest to real answer. (I bet it'll still be surprise – we're taking account of their power levels in Lanox, so at their current strongest.)
