Fun thought between the spirit blade and darkin blade

Just a reminder :I haven't read shens lore yet so I might get something wrong here. This is just an assumption based on my own perspective. It is just something I made up for fun so please don't get offended.

Anyway,I just thought about comparing these two and these are my thoughts:

Darkin Blade - a living weapon that takes over the host and desires to end the world, thinking that he would finally die from that. 3 Q casting abilities

Spirit Blade-a (living?) weapon that cooperates with the host and has the motive to protect and seeks equilibrium. 3 empowered Auto attacks from Q

I know it is not canon but it would be interesting if these two blades have something to do with each other(like the spirit blade is the mirror self of the darkin blade, or the darkin is trying to bring ruin while the spirit prevents it...as if the darkin is in need for someone to stop him or something like that.) Although, I wonder if the spirit blade even has a will of its own and a name...

Thoughts?
