I say yes it can be furnished. I say no, it may not be abused. It is a 'home', not a storage facility. Putting beds, chairs, etc is okay, Storing the PHB equipment section is not. Putting a dragons hoard of treasure is not.
Treebore said:However, if the PC had the treasure I don't care where they keep it. If they invested in or earned the fortress, bags of holding, haversacks, and portable holes, then why should I be unhappy with them because they use them smartly?
Henry said:The bags, 'sacks, and 'holes I would have no problem with, because even though they hold a lot, it's still a finite amount. On the other hand, a Daern's Fortress is a portable warehouse with no chance of loss or damage to anything inside, unless the PCs get really sloppy. It's not a problem to me, because I have rarely ever allowed the item into my games, unless the setting was appropriate, but it's something I could see getting abused rather quickly.
Henry said:The problem is, where do you draw the line without it looking like DM fiat (which it is, because allowing ANYthing in it when closed is not strictly by-the-book). What would be the reasoning for how "The Magic" knows the difference between beds, chairs and cookware versus hand-carts, ladders, and my sword-collection?
You can create any floor plan you desire to the limit of the spell’s effect. The place is furnished and contains sufficient foodstuffs to serve a nine-course banquet to a dozen people per caster level.
