Soran is the mysterious, cloaked emissary of Zaros. He can be found in south-west Varrock wielding a glowing ancient staff. According to Soran, if one chooses to follow Zaros, Zaros will act as a "dauntless, all-knowing protector". He will give various tasks to complete in addition to a banner of Zaros and a Book of the Gods. A title may be activated through this emissary to change a player's display to "[Name] of Zaros".
The top of his staff used to glow red, but was changed to purple in an update.
For a brief period after the Battle of Lumbridge began, Soran vanished from his post in Varrock. This glitch has since been fixed. A Jagex Moderator claimed on the forums, that Soran had simply taken a holiday to Oo'glog Recreational Relaxation Resorts in the VIP section that no one else could access, while addressing the glitch. During this time, the only way to contact him was through the banner of Zaros.
It is possible that Soran has the ablity to influence the Shadow Realm, as he can only be seen with a ring of visibity or Sliske's blessing on Tuska's back.
