Dragon Hoard/Lair

You conjure a door to your lair in range that lasts until you dispell it. You choose where its one entrance is located. The entrance shimmers faintly and is 5 feet wide and 10 feet tall. You and any creature you designate can enter the extradimensional dwelling unhindered as long as the door remains up. You can open or close the portal if you are within 30 feet of it. While closed, the portal is invisible. You can cast this spell again to move the door to your location if you still have it up. If DM allows once the door is placed and if you have regional effects those activate and once the door leaves the area everything begins to go back to normal.

Beyond the portal is a lair of your design. This uses the bastions system. If DM allows you can use lair actions while in your lair. The place is furnished and decorated as you choose. Any food stored here does not decay as fast and can last up to 10 years before going bad. Furnishings and other objects created by this spell dissipate into smoke if removed from the lair.

Once a week on the day the door was opened for one hour everything in the lair is repaired and refreshed as well as any changes you would like to make to the lair.

When the spell ends aka door being unsummond, any creatures left inside can choose to stay or go so long as you allow it. Anything you bring into the lair you can store there or take but items made from the spell cannot be taken out. While in the lair the door that you summoned cannot be unsummoned leaving the lair vulnerable and others can enter to and from.
