Obsessions aren't just for humans or orcs- Skaven can get them, too! For these guys, they're all about lightning- using it as weapons, as energy, as a decoration (they make their armor with lightning motifs); heck, they even amp up the smallest of their weaponry with lightning (read: cattle-prods that can stun a TROLL)! Naturally, there are a few problems with this lifestyle- death rates in Clan Ektrik are at an all-time high, so that's always a problem. Thankfully, the tons of engineers present means that upgrades for equipment are always easy to come by... but not without a price.
In Age of Sigmar, Clan Ektrik are apart of the Clans Skryre and have gained a new obsession; blowing up the Bad Moon with the biggest Doomrocket ever built. As per usual, their efforts had...explosive results for their laboratories.
