Undertale: Muffet vs Spider

So I was playing Undertale, and I remember at one point during the boss fight with Muffet she says, "Bla bla, with that kind of money, the spider clans can finally be reunited" or something like that. Generally, something about reuniting spider clans.
So apparently there were a bunch of united clans in the past, but something caused them to split up and scatter. So I decided to make my own little story of some of the events. This is just my own made up thing, like maybe there was a spider war, and before Muffet was ruling her own section of spiders, she may have been a fighter and shtuff.
Also in my little depiction here there are big warrior spiders.
