So, I'm level 18 (or something like that) and have been avoiding Preston Garvey because everytime I go near him in Sanctuary he gives me a quest. One of the ones he mentioned was 'Retaking Castle.' I ignored some of his other quests and eventually failed them. I was worried this was would fail too and so I agreed. Well it turns out Castle is clear the hell on the other end of the map from where I'm at and have run into a ton of interesting things to look at on my way there. Can I ignore him for now and explore or will he eventually die there or have the quest fail? Also this guy went from being a neat character with an interesting weapon to an annoying guy I'm doing my best to avoid. I should probably get a mod to fix him if there is one but for now I'll just be happy if I can ignore castle now that it's started. Thanks.

Preston has been asking me to storm the castle a long long long time ago, and along the way I've secured about 5 settlements, done all kinds of quests, started the BoS questline, rescued settler hostages, defended several settlements, unlocked 3-4 new companions, explored about half the map, gone to the Glowing Sea and back, and every time I see Preston he'll still ask (more in vain hope than anything) "are we ready to storm the castle"? I gotta admire his optimism if nothing else....

Yeah, I should have just kept him waiting too but I didn't so I'm heading that way now and ignoring a ton of neat looking places along the way just to make sure it doesn't fail now that I've started it

Storm the castle!! It is like the best settlement place in the game! Not only this but you get artillery in your settlements.

I completed it, but I don't see any artillery options.

Yes, think its an level or settlement number requirement for it to start.

One weird issue with the castle. I was sleeping off an radiation storm, then I woke up it was shooting, it was over after a few second and before I came out and found dead raiders on the top of the wall near the opening towards the airport.

Wall is repaired so they could hardly have scaled it except going trough the gate and this would take far longer than 10 seconds.

Does enemies spawn on the wall?

Anyway I have turrets pointing inward too, and as I understand the other turrets will then rotate and attack.
