[Untranslatable] have always known about the fact that many [dimensions] exist other than our own; only recently, however, have we found a way to [travel] between them. I am the first - and so far, only - test subject of this technology, and the [dimension] I have come to is really quite fascinating. I can return home at any time, but I would like to take some time to study this place, as there is no guarantee that I will be allowed to [travel] here again. Being a [scientist], I did come here prepared to [document] my observations, which I will do at frequent intervals.
Upon my arrival in this [dimension], I immediately found some structures that bear some visual similarity to [untranslatable] when we [morph] our appendages into many tendrils, covered in many fragile [wafers]; however, I quickly found that these structures are inanimate, and indeed, may not be alive at all. I would like to note, however, that they vary in size, and some appear to be smaller versions of others, so I hypothesize that these might be a type of [plant]. It will take time to prove or disprove this theory.
After further studying the area I have come to, I have concluded that there are many things in this [dimension] that are very, very small, and I cannot help but wonder if perhaps there may be still smaller things here which are too small to observe without [untranslatable] aid; unfortunately, this is not a theory I can investigate during this visit. The [ground] here appears to be mainly composed of a fine [powder], the composition of which I cannot even begin to guess at. Many small structures - some of which are no more than [untranslatable] high - cover most of the [ground]; if the large structures I noted earlier are indeed a local type of [plant], then these small structures are almost certainly other types of [plants], as they bear similar characteristics - some more than others, and most only in the fragility and [color] of the aforementioned [wafers] covering the larger structures. As for animate things, I have not found any just yet, and in fact have no actual proof that anything in this [dimension] is animate; perhaps everything in this [dimension] is stationary, and what I have mistaken for [plants] are actually [animals]. I will next attempt to get my bearings in this [dimension] by attempting to [traverse] it.
[Traversing] this [dimension] is not noticeably different from [traversing] my own, as the motions I am used to using appear to function perfectly well here. It appears to be virtually impossible to [walk] without making some amount of noise, however. At first, I worried that the fault was mine, but I soon [heard] other, similar sounds that I assume were made by [animals] moving around as well. If these sounds are what I presume them to be, then [animals] in this [dimension] are indeed animate, just as they are in my own [dimension]. I've yet to actually [see] one, however.
After [walking] a bit further, I have [glimpsed] a few creatures which have been quick to flee my presence, and they are very small - the largest I saw was only [untranslatable] in size, which is far smaller than the smallest known species of [animal] in my home [dimension]. They move quite quickly, however, and I was unable to observe much more than their sizes before they were out of sight again. The sizes of these creatures have varied from, again, [untranslatable] at the largest, all the way to [untranslatable] at the smallest - nearly so small as to be impossible to [see]! I'm certain there must be larger [animals] here, as these structures I believe to be [plants] are also relatively large, but I am prepared to be wrong.
I have found something truly fascinating: There appears to be a species of [animal] living in this dimension that is similar to [untranslatable]; at the very least, they bear a somewhat-strong [visual] similarity to us, much more so than these structures I am becoming more and more certain are [plants]. I have only observed them from a far distance, and will not do anything more for now. They are short - no more than [untranslatable] high, at least insofar as I have seen - but what they lack in height, they appear to make up for in width, and I would not be surprised if their weight is almost identical to ours. Like us, they have two [legs] and two [arms], though their movements are stiff and jerky, which I believe may indicate that they are unable to [morph] their appendages as we do. They have [heads], as we do, though many limp appendages that they appear to have no control over sprout from their [skulls]. Their [faces] are extremely distorted, and bear features similar to [untranslatable] - which, if they prove to be similar in function, would greatly contribute to what understanding we might be able to garner about them, as [untranslatable] are also somewhat sapient and can communicate with us. They are covered in strange flaps of what I presume to be [skin], though this [skin] seems strange, somehow. They also appear to communicate through sound, though what little I have [heard] of this communication seems to be almost uniform, so I cannot be certain just yet of how they convey different messages. Overall, they are…fascinating. I would like to know just how similar to us they are; perhaps they are sapient enough for our two [races] to communicate and share knowledge and items. They do appear to use tools, and I believe they may in fact be this [dimension]'s equivalent of us. Of course, their bodies and internal workings may be very different from ours, but…I would very much like to learn more about them. I believe I have found a significant argument in favor of making return trips to this [dimension]. I will return home now, and see what my fellow [untranslatable] make of my findings.
