Here is a fun revision of the raven queen otherwordly patron that was published a while back in UA. A patron asked me to make an improved version of it and I obliged. Raven queen is copyrighted material, but doesn't mean we can't make fun free stuff off of it for the community ;)
This one is more in tune with the aspect of her that likes to collect memories and gives you greater versatility.

THE RAVEN QUEEN
You are one of the emissaries of the Raven Queen.The whole existence of the Raven Queen was focused on collecting memories and strong emotions, typically associated with loss and tragedy. To that end, she dispatched her emissaries to the far confines of the multiverse to wait for such an event to unfold, as scouted by her ravens. These emissaries collected mementos, such as trinkets, memories from the living, sometimes the souls of the dead, and brought them back to her.
