Some players, myself included, have expressed the desire for our Respite to be portable in a way. As in, it could travel from Realm to Realm instead of being physically bound to one. But this is truly ridiculous, thematically and technologically. For example, the bigger our builds get, the more impossible this becomes.
So instead, how about a pocket dimension sort of thing? It would probably be unlockable in the endgame, and would only benefit the player who has it. No pizza parties in the poc-dim =(
But it could act as a portable forward operating base for someone delving in a very long dungeon. Maybe it's a single foundation large - just enough for a bedroll, a cooking station, and some storage bins. Almost like a mixture between the Stick Tent and the Pepys Box.
What if it came in the form of a ship that can travel between realms and within realms, able to carry large amounts of gathered resources and able to craft consumables needed in your adventure.
Maybe it can even grow and be upgraded as you gain experience and level. It could even have a portal inside it that can take you back to your estate and return you to the ship where you left it so you don't have to make the long trek back after returning home.
