Kelanen, Hero-deity Warlock Patron

Art by Harry Quinn

​So a Leachim the Learned shot an idea past me that I liked so much that I took it and ran with it. What if the Hero-deities of Greyhawk were Patrons for Warlocks in 5th edition D&D. Leachim was speaking of Kelanen, which would have been my first choice as well, and with collaboration from the Learned one, I wrote up this version of a Patron.
 
These are all works in progress, so if you have any ideas, changes, or suggestions, fire away, and I might alter them. I intend on making a Warlock Patron workup for each of the Hero-deities in the future, which one should I do next?
