[Vol.6] Ch.45 Mana Readings

  Tiberius's mas with the lead doped crystals didn't show any signs of health risks from operating the crystals, other than the risk of it as a projectile, so I felt fident we could try to grow a rger crystal that I could cut smaller pieces out of. So, I set up to have a 12-inch fluorite crystal grown, while I worked oing the smaller quartz chamber made to measure the mass of the crystal more accurately.

  The quartz chamber ended up taking a couple of days to make, since I wao use the most transparent quartz I could for one of the sides, so that I could see inside for bang purposes. By the time the chamber was dohe lead doped crystal had grown. From the ambient mana alo was very heavy. It's density was easily twice that of lead, or at least, that's what it seemed to be. That perceived density dropped in the pieces that I cut out from the rger crystal. In all, I cut out eight 2-inch cubes to use for the first set of manascopes.

  Since each of the eight cubes was cut from the same inal crystal, they should all have roughly the same properties. I even took the time to lihem up and file their sides down at the same time to ehey were as identical as possible for our current teology. I also then stoneshaped a stone cube to use as a reference size for any future lead doped crystals I might want to grow. Then, I took the time to start getting a mass for one of the cubes.

  That process took a day, si took a lot of re-opening the quartz chamber to add or subtract a small weight from the banside, then waiting for any mana that got in to be ed before cheg a new reading. Eventually, however, I did get a mass value for one of those cubes. Knowing their mana-free mass was important for calibrating any manascope I tried to make.

  The scope itself was actually fairly straightforward. I went with a triple beam bance scale as the basis for the design. After taking a cut crystal cube to the surface, it seemed like it about doubled in mass, so I set the scale's three bar weights up such that the rgest weight was half the weight of the cut crystal cube, and the two sizes u were oweh, and owo-huh respectively. For the purposes of accuracy, only the smallest of the weights move freely, where as the other two weights have notches they sit in which mark precise multiples. To make things simple, I then beled the scale in "crystal units" or "CU", based on the mana-less mass of the crystal.

  Operation is theively easy, one just moves the weights on the bars until the bance's needle marker reads as banced. That thes us get a reading for the ambient mana values in an area with fairly high accuracy, in crystal units. I built four of them, since I feel like having them avaible iain areas for making readings would be useful.

  I took a few days just making readings of mana values in different areas, and at different times of day. While the mana values don't ge quickly at any given point in time, they aren't stagnant, and I quickly found that if I just left a bahat was level alone on the surface for about fifteen minutes, it was visibly unbanced again. I suppose I shouldn't be surprised though, since I know that at night time our mana regen rate is lower than during the day.

  The highest ambient mana values during the day are at noon, whewin suns are overhead. Then, the mana value from the manascope reads 2.315 bsp; The lowest ambient values, excluding eclipses which I haven't yet had an opportunity to measure, occur at midnight, at 1.12 bsp; I've known about those differences ever since I've been out in the world regeing mana, however. I've eve in a plenty of times with the stirling engines w slower at night than during the day. Unsurprisingly, there is a sharp drop off after su, where the mana value drops 0.31 just a few minutes as well. Though iingly, it seems like a little more than half of the ambient mana value es from the smaller of our stars.

  Underground however, the mana values move much less based on the day night cycle, though they do move a little. The mean value in the fluorite growth room is actually higher than I expected, despite only being 1/1000th the mana regen rate. If it was 1/1000th the daytime rate, I'd have expected 0.002 CU, which would have been unreadable. Instead, I measured 0.095 CU, or about 1/20th the level. It was quite a bit higher than I expected, so I was worried that maybe the room wasn't as mana proof anymore. So I tested my own mana regen again in the room, and got the same value as before, about 1/1000th the surface regen.

  That would expin why the fluorite we grew down there would still exhibit properties as if exposed to signifitly more mana than I had thought. On one hand, I'm gd that I actually did try to measure this accurately with a meical device, oher hand, it's opened up a whole bunch of new questions. I'm regretting that the testing b down here is partially dismantled aroyed, because I'd liked to have seen what the ambient mana in there was, by parison.

  My w hypothesis is that our bodies actively use a certain amount of mana, and so the value of mana I see as a stat is only actually free mana that I use, minus some ft value that my body uses. Though it might not eve. It could be survival based, where the body uses more mana if it , but only keeps vital systems going in low mana situations.

  It's a shame I didn't have the manascope developed before I took the surface crystal away, because I'd liked to have seen how it affected ambient mana levels on the surfabsp; I could, at least, verify that the mana levels near our 2 foot crystals were higher than the areas further away from them, but underground crystals generally don't leak that much mana into the air, and we usually use them in ju with water as a ductor for the mana.

  I did, in our boratory setting, submerge one of the scales to very slowly try to determihe crystal reading there. As it would turn out, the bances I had made 't read the value. I maxed them out. I'm not that surprised though, as the mana regen rate when toug a mana crystal is incredibly high normally. I'm going to make a bah rger weights to try to measure the mana crystal values .

  For the high capacity manascope, I took two days to make it and the precision ends up a bit worse in order to keep it paough for transport. I ended up getting a reading of 15.6 CU for the the 2-foot mana crystal and water setup. Whies out to about 6.8 times the noon mana regen rate. Of course, that all assumes that this ends up being accurate fer mana rates. I've seen some evidehat fluorite crystals, especially smaller ones, seemingly level off in their effects at higher mana amounts, when they are seemingly saturated with mana.

  For simir reasons, I'm now sed guessing the readings in the fluorite crystal growth area. It could be that the crystals also have an outsized effect at low mana levels, and that their efficy simply drops the higher the ambient mana is. I have devised an experiment to gain insight into that. I'm going to use a heat fluorite crystal, a bunch of quartz blocks, a thermometer, and a rge pieetal.

  My pn is to use the heat fluorite to heat the metal for a fixed period of time in a chamber of quartz blocks. That chamber will be set up like the old freezer design, where I pull a full side off quickly. I'll check the temperature after a period of time, and thehe metal cool after rec the temperature. I'll then remove some of the quartz blocks, a the experiment. I'll perform it on the surface at the same time each day, deep underground, and partially underground, to get multiple locations of data.

  Then, I'll plot the various data points to see if there is any differen the liy of the data. It's not foolproof, but it should at least provide me with some amount of insight into what's happening.

  The whole experimental process at all the locations ended up taking just over two months time. Ultimately, the lower mana enviros seem to be fairly linearly linked, showing no signs of any ge as the mana level rose. On the surface, however, I did notice a very slight downward curve in my data readings, but given the ambient temperature ges day to day, it's hard to determine if that data was just noise or not. I'd o have the experiment run for months oo try to get the .

  It did, however, make me fairly fident that in low mana enviros, the lead doped crystal is probably reading accurate values. Meaning our fluorite growth area is most likely getting more mana than I had previously thought.
