Arguable on three points:This is an interesting one, because even if we can take the big boss killing those guys would obligate us to move to Vegas. Which most sensible people agree is a fate worse than death.
1) We might be able to kill or suborn whatever it is on the other side. We have spirit killing charms, which are very setting in the setting, and we are exalted, which might matter, depending on what's out there.
2) We might be able to close the gate. Depending on how it works, and what it is, Sapphire Ritual of Exorcism might destroy the connection between Reality and Outside. It "splits apart any unnatural joining of matter and spirit". There's nothing more unnatural than a connection to the Outside
3) We might be able to replace Sin Eater with a custom god of our own design. Raise the god of Las Vegas, empowered by all the sin in it, and command it to guard the gateway.
I hope not. We have actually voted on Carpenter presents, not all presents, as I understand it.Incidentally, are we past the point where that booze vote could go in? The original gift plan vote had something for them, and I'm not clear if this last vote was just for clarifying a few people or if we discarded that and only our votes for the latest gift set count.
