Zogar

Zogar is a powerful yet eccentric chaotic wizard who has at different points set up lairs in mischievous places in order to gather minions, wealth and power. He projects magical eyes to watch over his vast treasure hoards and his many enemies.

The paranoid wizard hasn't been seen in person for decades, not since he lost his eyes in a duel with a lawful Wizard. He prefers to hide in lairs, sending his many supernatural minions summoned by his enchanted horn to do his dirty work. Zogar refuses to summon imps, as he thinks the creatures aren't worthy of him. Instead, he summons Darklings to do imps work. As a result, his Darklings are constantly bickering over which one of them is in charge.

Zogar's end goal is unknown, but it is clear that whatever the evil wizard wants to achieve, it involves amassing a lot of wealth and magical power. This much is made clear by his obsessive collection of tomes and treasure, the size of which never seems to satisfy him. However his allusions to what he calls his "devious plan" suggest that all this is intended to serve some greater purpose than just wealth and power for wealth and power's sake.

The Black Mountains
No one recalls when he arrived to the region, but his presence slowly altered the landscape. He quietly made his home in the Black Mountains, where many ventured in search of rumored treasure and in quests of glory. Few returned, and the legends only grew. His lair became a destination for all those who sought fame, knowledge, and riches. But only the bravest of adventurers could withstand the baleful gaze of Zogar. He eventually had to relocate after the increasingly frequent raids which were becoming more and more successful with time.

Otansphar
Zogar and his minions sought refuge deep in the Black Warrens of Otansphar. It was not long before the wicked wizard began his plotting against the humans above. His first order was to steal the crown of the king to create panic in the city, replacing it with a paper crown with an eye drawn on it. His plan worked.

Now brave heroes must enter Zogar's vile lair to recapture the crown and restore order above.
