OOC Note: Branch does not write much unless he needs to for professional settings and the like. Instead, he tends to sketch his feelings out, so you'll probably see more of that instead of actual writings. Feel free to try and interpret them however you'd like.
On another OOC note, this journal entry is from near the start of his roleplay. I got to it a little late.

On the page, there seems to be detailed sketches of a black rat and Branch. In the sketch, Branch is sitting down patiently with a blank crystal shard in hand as he attempts to charge it in the sketch. Meanwhile, the rat seems to be standing up as she imbues a blank crystal shard with some type of magic that flows evenly into the crystal, which is what Branch seems to be trying to do. In the background, the Morenth Library can be seen as well as a few extra crystals and fire crystals on the floor. Sketched light can also be seen shining in through an entryway. The expression of Branch seems to be one of indifference, but somehow, it's made clear that Branch was actually very interested, probably from his eyes and focused gaze. Meanwhile, the expression of the rat seems to be blanked out, as if Branch was unsure of what was going on in their head. 

Below the sketch lies the sentence "Good learning experience, thank Mireluch later".
