Are there any chaotic or neutral gods (inc. empyreal lords, eldest or anything else), of learning and knowledge? I'm creating a Gnomish Summoner for an upcoming "Shattered Star" campaign. He's a scholar and explorer who has fixated on unraveling the mysteries of Thassilon and the monuments around Magnimar, but I can't decide who he would worship. The nearest I can find is Irori, but he seems too humorless for the concept I have in mind.
