Krenn, The Cat of Midnight

"That we could stroll through the moonlight, and only happen upon gold is certainly plausible. If violence should have been done to a man under the same moonlight, who happened to lose his purse, well...that would certainly be bad luck." -Thieves Cant taken From an Alleyway in Zarlo
Krenn is a most mischievous cat, once a Patron for Warlocks of Trickery and Greed, Krenn became the Diety of Thieves the world over.
Krenn might be watching you anytime you see a Black Cat, Krenn's eyes see every coin purse dropped and ever document forged. The Patron Deity of Theft, Forgery, and corruption.
Krenn appears as a black cat with one eye of silver and another ocean blue, they will generally wander the mortal realms posing as a normal black cat and tricking the mortals into attributing their power elsewhere.

Divine Origins

Some say Curiosity Kills The Cat, but what if the Cat Finds its' query before it dies? What if That Cat was curious about how to steal a legendary Orb, one that Glowed Red and Promised the Power to become unto a God?
Many Able-bodied Adventurers Quested for The Orb of Might. Some had great strength, others great agility, some had amazing magical powers...but Krenn had what they lacked: Luck, and lots of it. 
Krenn is the most curious of Deities, as Their followers have more say in many ways than themselves in how the Religion is shaped. But the paws of Krenn will grasp the purses and claw the eyes of those who seek to expose the sneaks. The Thieves guilds of the world find riches beyond reason by following Krenn.
