Nice! This brought to mind the old MoonHunter series of articles on Mage "tools" of the trade like the Solomontic Rugs and Shadow Shrines. The thought that seers and mystics have such hidden chambers secreted away in large cities is also an inspiring thought...
The library wall-shelf pivots and opens up into an eerie chamber of mirrored walls, floors, and ceilings. "Yes", says the Baron, "This was my great-aunt's secret room. We still do not know what she did inside, or what the room was used for..."
The imagery of a mage in a mirrored room, communicating with reflections of spirits and gods know what else, is a great one. And of course an obvious plothook, but i have to mention it, because I immediately pictured it...PCs get trapped somehow in the mirror-maze of dimensions (even though it is a communicating chamber I know). the mage has to help them get out, while they encounter countless spirits and obstacles in this multi-dimensional world.

I really like the plothook with elves using this in a millitary manner. Though I am curious as to how a plant would be able to hear sound, though I'm sure there's an example somewhere in wikipedia for that as well. Go to Comment
When the rat pods exhaust what food is available they are likely to swarm. And another thing to consider is that there is a cost for their mobility, they have a short lifespan as seeds. While a regular seed can survive dormant for a long time, rat tree seeds can only survive for a few weeks at the most before perishing.
And things that eat seeds are definitely going to be going after these running nuggets. Go to Comment
Odd and flavorful piece of flora! I like the fact that it has "weed-like" properties, ravaging the terrain, to ensure its own proliferation. Perfect trait for these, "vermin of the plant world" to have.
