It is something of a plot hole in horrortale about why they're still trapped when there's like hundreds of corpses in snowdin therefore more than 7 human souls. Hell a monster needs to consume ONE for them to past the barrier alone
The explanation WAS that Sans was deliberately stopping anyone from consuming one and since most humans don't make it past Snowdin that's why, however recent panels show corpses in Hotland & Waterfall so it's a bit odd no one else considers the idea
But ngl I'm curious what happened to the souls if they were never gathered, I assume if you don't have Asgores magic soul container jars they just vanish eventually. However I'm curious since Horror has no motivation to cross the barrier himself if he ever consumed one for himself for a niffty powerup
Be an interesting explanation for why he's powerful enough to get on Nightmare's radar (though im aware horror joining the bad sanses has always been pure fanon lol)
