Fun fact about druids - in their tradition pretty much every break from the norm, like writing things down or cutting herbs wrong, was punishable by being clubbed to death.
Fun fact two: In France Druids were exterminated by Romans with help of Bards. Bards were basically a competting sect of the same faith with Druids and they sided with Romans to save their own skins and eliminate their rivals.
So what I get from this is that Tyr is a bro and Volo sucks.
