[SPOILER] Who is "my love"?

[Modular100]

As far as I'm concerned, and I'm ears deep in this thing...

Spoiler below!

it's Alexander's beloved one waiting for him (unsure about him/her waiting though...) in his homeworld. It's not exactly sure what the stones are for, and if they allow him to in some way communicate with this other world or if it's more of a diary that he keeps to himself. Since they can be found all over Brennenburg, the latter is probably more true considering how Daniel's journal is scattered over the castle (I never understood how the pages could ever get down into all the prison cells).
Also, the age of these stones is unknown. For all I know they can be centuries old.
I think the LevelEditor mentions the stones as EmotionStones or MemoryStones, I'll have to check it!
Hope this wall of text helped you a little
