I introduced Maavu to my party through the organisation I called 'The Acquisition and Exploration Division of Dorcemenary Museum' or the Acquirers for short. Have a look at the organisation in theRPGenius.com if your interested.
Basically one of the players was accepted into the 'good thieves guild' and the party were invited to a game night. Here they played a dice game but more importantly meet with many of the guilds allies including Maavu and Skie.
This games night occured just before chapter 4 and allowed me to foreshadow Maavu's hatred for the taxes and belief that the governmwnt was corrupt. It also allowed me to provide the party with a practical reason to be near Maavu's warehouses when the Umber Hulk struck.
When most people had left for the night including Skye, Maavu invited the party to see his new magical wares before he sold them to Skie the next morning. The party were eager so just as they approached the warehouse, the Umber Hulk exploded out of its wall.
Have a look at the document. It may be appropriate for one of your characters in the future.
