After almost two years in the game, Roland spent most of his time either doing magic experiments or reading books.
Books on magic were naturally his focus.
There was a lot of common knowledge that could be gleaned from books.
For example, regarding Duncan's (Mordenkainen's) place in the world of magic.
Compared to the mundane world, the magic world still had a bit of recorded history; after all, they were all intellectuals, and some of them had intentions of passing down their legacies.
Besides, some spells were named after the inventor.
Mordenkainen invented at least about a third of all magic, according to what was now known, and all of it very practical. It could be said that to become an Elite Mage, you would have to have learned at least one spell he invented.
For example… Hand of Magic.
Or, Magic Shield.
Amongst higher level spells, more than half of them were his inventions.
