The Sinister Six
Skywalker (true name unknown) is an elf mage from the city of Quellen’dair who appears to be a powerful spellcaster interested in helping the party battle against the effects of the Elder Evils. Apparently a mage of great standing within the city’s arcane guild, Skywalker commands the service of genies (and appears to have air genasi heritage) and resides within the great crystal tree which forms the Quellen’dair Schola Arcanis, a sort of highly-advanced equivalent of a mage’s guild.
After a series of adventures with the party, he appears to be functioning as a sort of benevolent patron for them, often providing spellcasting and magic items. With the defeat of Skinwalker, he is now apparently a new member of The Sinister Six and in control of Villia.
