It is really not the magical objects that is nagging me. The magical objects in Astlan is quite ‘standard’ fantasy fare. What does disturb me are the ordinary nonmagical objects like the books, Damien’s glass top table, the wine bottle, the locks, etc. From what I can refer, they are modern objects instead of the more appropriate medieval versions… which essentially should not have been used that much because these objects are uncommon and expensive in those times.
I was also bemused in how advanced they have in knowledge about electrons, protons, neutron and they even know quarks… but they somehow has no knowledge about nuclear reactions (Lenamare’s nuclear bomb). These elementary particles and quarks are discovered and observed using nuclear reactions, usually controlled in particle accelerators.
