The biggest mistake of Lightfall is that fact that it simply refused to actually establish stakes. At the very least we should’ve learned what the Witness intended to do and how the Veil fit into that plan, so that when that final cutscene happens we get the same feeling of dread as the characters. Instead we only learned about the Witness’s origins in a cutscene not even tied to the seasonal story it was released in and learned about its goal from the TFS showcase. The -blam!- chapter of your big story isn’t the time to introduce new characters and a new setting like Neomuna, while diluting the story with too much focus on the new subclass. Ironically enough Stasis was better implemented in Beyond Light, because the point is that it’s simply a tool. We know Eramis wants to take revenge on the Traveler and we’re shown how effectively the House of Salvation wields it. Even Calus suffered from it, with only two interactions with his daughter he hasn’t seen since he was exiled. Caiatl remains outside the complex to try and delay her father and we get NOTHING from that. The fact she survived betrays some remnant of love on the part of her father, but we don’t get to see that! Could’ve easily had a Tormentor go to kill her but have Calus order it not to, because the Veil is all that matters. You could have Caiatl realising that her father is less allied with the Witness and more so being compelled by sheer fear of the God he has shackled himself to. Which continues that degradation of Calus we see throughout the campaign. It’s absolutely heartbreaking that’s how he went out.
