So I've been playing Destiny 2 on and off since launch. I barely played Mercury because I thought it was the most boring DLC I've ever played and I didn't buy the Season Pass until it went on sale recently. But I'm excited for October 1st and I've been playing catch-up. I'm trying to finish off as many quests as possible and watching YouTube videos on how to do these things, but many are outdated and I can't finish or start certain quests. If anyone can help out, that'd be awfully swell. Here are the 3 things I can't seem to do: [b]1. Mercury's Weapons Forge.[/b] I read that you have to complete the main missions, which I did at launch and then do ONE Hard Mission and Brother Vance will give you the first step. I did all 3 Hard missions and nothing. Is this something I can never do now? [b]2. The Truth Quest.[/b] I read that you get this mission in a chest from the Menagerie. I've done a few... nothing. Do I just have to keep doing this until it drops? Do I need to do something else first before it'll appear in the chest? [b]3. The 3rd Seed of Light.[/b] I guess you are supposed to get this either by doing a Raid (never going to happen for me) or get the quest called Between 2 Worlds, do some Blind Wells, then go to the Observatory and a portal opens after presenting your offering. I did it last week—nothing. I did it this week—nothing. Is this something that can only be done at certain times or is it just gone?
