Currently the area Boreal Keep (Maze Entry) has one chest which can hold 10 items. Given that the area's main in-game use is for artifact RP, it would be great if there was a bit more storage to make it easier to keep non-fixture items in there as right now it's low enough that you can't really fit much in.
The inner Maze area could also use some item storage as RP-wise it's used for containing highly dangerous items, so some sort of item storage inside would be very useful for being able to RP that with customised or unique items rather than just fixtures.
