Probably some of this is in game somewhere, but anyway...
"scientists" are mentioned among the Xacha in connection with their history and religion.
Are these scientists still around?
Is this actual reliable science, crackpot nut cases or forgotten lore?
Does Xacha science generally focus on technology, archeology, botany and zoology, thaumatology (as in scientific method applied to magic), or some other field, or is it just "scientific reasoning", or hypothesis, theory, experiment, conclusion type scientific method applied to whatever?
What is the relationship between science and magic?
Is an Yliakum scientist likely to reject magical elements of a new discovery or technology?
Is an Yliakum mage/alchemist/etc. likely to reject scientific explanations of how some complex thing works?
Are there devices incorporating both high(er) technology and magic? (not computers, etc. perhaps, but let's say an autonomous golem powered by a steam engine but controlled by magic (the first steam engine that I know of was built in Greece in something-or-other BC, so if we're going for medieval, it still fits))
Exactly how advanced is science and technology in Yliakum?
Which fields are they stronger/weaker in than others?
Which fields are currently advancing fastest?
Besides Xacha being generally good scientists and mathematicians, which races are better at scientific research in which fields (besides Xacha)? For example, Kran might be expected to have an advantage in geology, while Diaboli might have an advantage in metallurgy from dealing with various molten stuff in their homeland.
What races are already more advanced in which fields or are they all about equal (share information equally)?
Are there fields in which knowledge has been lost?
What knowledge?
What evidence is there to support this?
Is this knowledge likely be reclaimed?
And repeat all above questions for magic, where appropriate...
