Out of Dimension Towers????

[Matafuego]

In a campaign we have been playing for several years (with a conversion from 2e to 3e and then to 3.5e) a lot of wizards (yes, we had lots of wizards and lots of players that couldn't adventure / play every day) are reaching high levels and have inherited a missing wizard's tower (the wizard is a now dead pc).

They are collecting lots and lots of coins in order to make it bigger, but not physically.

Ever since we started playing dnd (and I was a player not a DM back then) we heard of wizards who had 20x20 towers but that on the inside they were actually 100x100...
Is that doable by the rules?
Have you seen it done?

I want them to be available to make it but I don't know what guidelines to follow because I don't want it to be extremely cheap, nor the opposite...

Any help or ideas???

Thanks in advance

Well my guess would be that you don't actually enter the tower like it seems you do, the doorway would actually be an entrance to a demiplane, which is layed out like the interior of a large tower or perhaps each door/floor links to another demiplane in the series. Basically a 9th level Genesis spell/power and some kind of permanent or triggered portal to that plane. And enough time for it (the plane) to grow, though you might want to allow them to research a spell with a higher cost in material components or XP that grows faster.

And real estate could be REALLY cheap in, say, the Abyss or the Hells. Of course, you'd have make your tower much more defensible. Come to think of it, the Ethereal Plane might be really good. IIRC, teleportation spells "touch" the ethereal (or was it astal?) so it would be a good fit. Also, the poor visibility on the ethereal would limit the tower's discovery by potential intruders (you could even place it in the deep ethereal to further reduce the chance of discovery).

I've never actually seen this done, but it really sounds like to me that in effect the tower is a magic item of Mordenkainen's Magnificent Mansion. (note that the effect is somewhat different in that you will probably have many windows and doors from the extradimensional space, rather than just one--but that's permitted for magical items).

I have no idea what the price should be; I'd start with a continuous M's Mansion spell cost, and see if I thought that was reasonable.

Note that smarter players will probably want to build in some kind of defense against Mordenkainen's Disjunction as well...

The idea of putting it on the planes seems good but I don't think my players would dig that =\
The Mordenkainen thing is something they'll enjoy more I guess...

Personally I was always a big fan of the Guards & Wards spell from 1E but I don't think it even made the 2E cut let alone 3E. Didn't do teh size alteration, but it did make your tower creepy and better defended.

Guards and Wards is in 3E. It is cool.
