Retreating to her armchair, she settles in.
It doesn't take her long to figure out that the writer is talking about dream powers like the ones she has (which they say are the mark of a "Conduit"), and a cozy cave house not too different from hers. They call it a "Bevin", and the links between worlds "bridges"—that did start to seem like the right word after she'd been struggling across them for a while—though this person seems to find them much less of a struggle, or is maybe just eliding over the few minutes of effort every time.
Many of these worlds are ones that don't appear in her dreams at all. Rorch, Yomi, Crucible - she kind of hopes she never meets the latter two, though Rorch sounds kind of okay.
Others are more familiar. Brazen, the brass place. Arbor, the starlit forest. Earth, of course, which seems to also be where this person started.
The bleak plane of marble seems to be called "the Prison", and is apparently full of unknown beings encased in stone, and stone that tries to encase you if you stand still for too long, and trees that send blobby rubber minions to attack you if you disturb them. She thinks, perhaps, out of all the worlds she needs to build deeper connections with, she will leave that one for last. In fact she might leave it for never. She can decide when she gets that far down the list.
The writer has heard secondhand of a world called "the Academy", but has never been there, and the few details they've gathered are not conclusive enough to tell whether they mean the same Planet of College Girls she's been to. Still, Academy is admittedly a nicer name.
A few other tidbits of information sound useful to know: connecting to each new world costs more world-investment than the last, if you're not the special kind of Conduit that's good at wandering. She thinks she is probably not that kind. There is such a thing as a "Crown" you can have in only one world, and can't change worlds once you've got one, and it provides all kinds of benefits for that world in particular. She thinks she probably doesn't want one, but it's still good to know she has the option. You can mingle the powers of different worlds together to get something better than what you started with, but it costs the same kind of time investment that you'd use to connect to worlds and accept their powers, about a year's worth.
