I've already submitted the Hammerlandese Rekenarim character I posted here, some two weeks ago. Have not heard anything since then, but hopefully it gets accepted and published eventually.
As for an evil adventure - you will need more evil characters. To date S&P has only published one, the Cener Druid of Ruel - for a full adventure, you would need at least one each of the warrior/ monk/ mage/ rogue/ ranger classes to give the players some variety.
Actually... *ponders* The preface to LW 13, "The Plague Lords of Ruel", mentions an assault on the Cener fortress of Mogaruith that involved 7000 men... and only 70 managed to make it back to friendly territory. Using the Cener Druid as main class, one could write an adventure that portrays the Cener perspective of the invasion, and revolves around a group of PC's having to accomplish a series of tasks in order to stem the invasion successfully. Of course, LW 13 also mentions that there were Drakkarim and other Darkland characters housed in Mogaruith, so one would expect to see them available as classes too.
