Craftmas Chaos Trouble (spoilers?)

So one time, when I had some time on my hands, I decided to try to solo the craftmas chaos quest. Once I finally found santa, as well as searching for other things, I admit some wiki pages and youtube videos helped, I... ended up dying to the last boss in the quest. You see, my main weapon at the time (maybe White Ghost? I know it was a 2 EB dagger you get at a town's weapon merchant. Maybe Detlas) did mainly wind damage... which is what said boss resisted. As such, I ended up dying. Now, if I ever were to try to sail back to the original chimney portal, would I be able to continue the quest... or would I also have to restart it from past selchar and stuff?

Additional question, can guilds capture future/past selchar? :3

 

As far as I remember you'll have to visit Santa again, proceed to Past-Selchar and make your way through the cave, to access tue Future-Selchar and the boss fight again :3

 

Do I get any quest items that are needed for other quests? Because I may just not go through the trouble again XD

 

No, you get a piece of armour and the usual xp and emeralds mix
