personally, i use home in a hat by Elianora its ala Staff of Shalidor but smaller, having LOTD installed, pretty often i get too much weight and helps having a portable home where i can dump all that shit and fast travel/ not walk like a slug.

yes it does include it, however i have not yet seen the interior and i cant tell you how it looks nor how big it is, the wiki has more information if u want to look at it here

funny enough i used elysium before home in a hat and i loved it, but recently, after starting a new save and having lotd installed too i didnt see the point in having more than one "trophy wall"
