...And yet you think siding with Larius makes the most sense?
Well, given that Larius isn't saying "hey, let's play with the big dangerous monster, no, no, man, it's totally cool, nothing could possibly go wrong", then yes. Basically, if Larius is wrong, then the worst that happens is the status quo is maintained. If Janeka is wrong, then you are potentially unleashing the Blight to end all Blights. Plus, with Larius, it's a WYSIWYG kind of crazy...Janeka's a more subtle, but still obvious, kind of crazy. She's the worst kind of threat: the kind that thinks she's helping.
Granted, that all goes to pot anyway when Larius changes his mind about just ensuring the seals stay sealed (which isn't a reliable plan, granted, and half the reason that, as noted above, I sided with Janeka anyway) and, as noted, the two end up doing the exact same thing.
