It is said that evil begets evil in perverted forms, and such is the case with Exodus, the claimed bastard "son" of Mondain and Minax. This faceless enemy of Britannia masters bizarre forms of technology, and was able to create hordes of gigantic clock-work golems accompanied by flying metallic devices.
This threat rose from the lands Ilshenar, which was connected to Britannia by the moongates in Gilforn's experiment. Exodus relayed on the workforce of enslaved gargoyles and alliance with bittern Lord Blackthorn to expand it's influence to Britannia. This invasion was however halted with the lead of court mage Nystul and his casting of a counter spell to nullify the dark magic attacking the realm. This was however not the end of Exodus, far from it.
Although the Gargoyles were freed from their slavery, Exodus kept a strong foot inside Ilshenar and began to toy with time itself. With power combined with Lord Blackthorn, this fiend was able to bring back ancient warrior race of Juka and indirectly Meer as well. But the final results of this conflict are still to be seen.
