What would your dream DLC look like?

Dragon and themed DLC.  Dragon companions, both rideable and cat size.  There is dragon and fantasy themed CAS, decor and furniture items.  I'm thinking a mixture of classic fantasy and Napoleonic area stuff because I love the Temeraire novels.  Kitchen and bathroom items would be functional both on and off-the grid (there is a toilet to match the sink and bath).  The pack would have cross-pack functionality between all the occult packs, for example expanded uses of occult abilities (not sure how).  Dragon colouring can be customised in the same way Cats and Dogs can have their fur customised.   There is also an option to use notebooks or scrolls to write books, and a messenger pigeon (or other bird) to send letters.  The pack comes with a new world that features an olde world pub, a dragon training arena, a themed museum and other communal lots.  Sims can obtain dragon eggs and look after them until they hatch.  

The pack has some cross pack functionality with Royalty and Legacy (which i don't have yet so I can't quite say how).  Get Together clubs will have new options depending upon pack skills.  Sick dragons can also attend the vet the same as cats and dogs.
