On the walk out of the park, Rian is able to obtain a basic selection of nouns and a handful of verbs, mostly regarding movement, and this vocabulary expands to include various features of the city environment as they exit the park and ride off down the road. It doesn't take long for Rian and Orochimaru to become more or less conversant in the local language.
Additionally, as the cart ride goes on, Rian is able to observe the transition from 'night' to 'day' first hand. It is honestly more like passing out from underneath a cloud than it is the dawn they're familiar with. With suddenness enough to almost disorient, the sun reveals itself from behind what looks like the moon. It's a bit of a surprise when Rian sees what appears to be a second moon, behind the sun, and looking closely she thinks she just might be able to make out some texture to the sky itself? Odd, and maybe something to look into later. Certainly, Rian has been sent someplace else, not simply some distant location of the normal world.
A while later, the cart approaches an enormous tree, almost as large as some the giants which are scattered in and around Konoha, though this appears to have had it's heartwood cut out and been turned into something like a hospital rather than left pristine. Standing outside are an elderly man and woman, the man with long black hair and beard and dressed in white silks, the woman white-haired and dressed in purple and blue. The presence of those two seems to set the woman leading the group on edge, and after the cart pulls up, the elderly man gives a curt, indecipherable command to the woman, possibly spoken in a second language or else maybe just a code-phrase. The woman and the underlings dressed in white disembark, but the green-uniformed ones do not, and the elder woman boards before the drivers set the cart moving again. The woman turns to Rian and speaks to them, first establishing how much of a vocabulary they have, then once she is satisfied with their conversational ability, she asks, "Who are you? Where did you come from, and how did you get here?"
