Good one. How about:

a) Red Prince's origin and the whole debacle it raises about the identity of Dragons (whether they were created by Ouroboros as by Patriarch 's words, or regressed into lizards and whatever Zorl-Stissa had to do with the ordeal)

b) Souls and Spirit Vison, Mindread (Source Abilities) being canonically present in Dragon Knight Saga after the so-called 'purge'

c) which should be just b.2 - Dragon Knights and Dragons (who are Source-dependent beings) still existing and utilising powers after the 'purge'. Also the Sentinel Island? The place that manifested consciousness due to an abundance of Source?


The only one treasure worth digging for - knowledge
