[The video starts and you see Rose. Behind you can also see that she is in her room in Liege Maximo's temple. To her right, on a human size table is a pile of lumpy looking clear crystals, with a new robotic firelizard pawing at one of the said crystals. Rose herself is holding a crystal as well, so that the camera has a better view of it.]

I wonder, does anyone know what these are? They are much denser and heavier than what one would expect from an ordinary crystal, thus making them quite strong.

[She already tried to cut one with the Dragon Buster, but it took quite a bit of effort to get part way through.]

I already have a few ideas of what they can be used for, but I would like to know their main purpose. That is, if they are also present on other Cybertrons.

If anyone is interested, I know where there are more of them, as well.
