So I just started moding last night, I found a link on the morrowindNexus to a steam GOTY construction set and I watched a few tutorials. Now what I'd like to do is make a quest, a quest that in turn gives the player a new house but I'm not sure how complicated that would be, here's a few of my ideas and I just want to know whether I should try something easier or what not.

Quest starts off by finding a book, a journal that tells of something bad happening to someones friend... because that's what journals in TES do is kill people!

You go into a cave (which I would like to make from scratch... not sure if I can...) kill some stuff, talk to somebody, do something for him etc...

than in the end the cave will become the new player house...

again I've watched a few videos so I can place buildings and mod terrain but i'm worried about the book, making the cave and people. oh and keeping the cave/home free of enemies.

My first question is; The cave building in morrowind construction set, is it the same as what they showed in the Oblivion 5th anniversary edition bonus disk were it's "like a lego set on for caves"

Thanks in advance guys, if it's to complicated maybe tell me some ways to get more practice!
