B3 - Palace of the Silver Princess: Aftermath
by Marc SaindonWhile placement of the module is a bit of an issue, one way to place it in the Adri Vahrma Plateau (nw of Glantri) is to assume the realm 'bleeds' into the Feywild (a 4e concept, although pocket dimension can also work) and during the playing of B3, your characters can't escape until the quest is done. Geographical inconsistencies can be attributed to the 'Firchlis', a magical of change that alters the landscape (a concept I'm stealing from C:tD).
Once it's done, and the Princess is freed, the realm of Haven can then go back to normal... which means it locks back into physical reality and next door to Glantri.
A continuation possiblity is that Haven and Glantri renew contact, with the Princess Argenta claiming status as ruler of a Principalty (Haven) and now having to play the game of politics outside her realm, and mandating the PCs to handle the missions.

On the pre-generated characters in B3 (p.3), Clerics, Dwarves and Halflings might be a problem in Glantri... so Clerics become Human Druids (replace chainmail with Hide armor) or Human Ministers of Rad (Clerics of the 'Rad' religion; Dwarves and Halflings become Gnomes. Because Gnomes are presented with a dutch-like culture elsewhere, and they are present in french-speaking New Averoigne, perhaps they have a belgian culture (if one is capable of making a belgian accent) like JCVD.
