There are probably no gods who are completely good acording to "modern standards".
A few days ago, I read here this post on the /r/DnDNext subreddit talking about how Corellon is kind of a dick, and it gave me the idea to "test" the faith of the cleric one of my players is currently playing. They are a fairly devoted cleric of Oghma (Knowledge Domain).
I've been trying to find some things Oghma did that could be presented to their character to "spice things up" with their god; however, I've been having trouble finding anything specific on Oghma, seems like a fairly neutral god who doesn't really get involved in anything.
So for all the lore experts out here, what controversial things has Oghma done that you'd recommend sharing with this cleric to test their faith?
