Blood Crystal Great Sword, old Twitch drop?

I mean look at it that sword looks incredibly cool. I read from the wiki that it was a twitch drop from last year.

Is there any way to get it in-game? By that I mean, did it ever show up on the Bazaar or in a season pass? Would be a shame to lose such a nice weapon! If not, are there any greatswords or weapons similar to this (including mods)?

Cheers
