Signature Heroes are characters who will accompany you within the game (particularly upon future quests). They were first announced in the Developer Blog "Who are the Signature Heroes?" There are a total of six Signature Heroes (seven including the player). An update caused all the heroes to wander around the world, and gather at the Champions' Guild, Heroes' Guild or Legends' Guild (the Raptor is only in the Legends' Guild).
List of Signature HeroesEdit
Ariane is a powerful magic user. Raised in Seers' Village, she retains the power of precognition. She has studied in almost all schools of magic and excels in all of them. She is curious about the ancient magic of Gielinor and is determined to find out all about it, despite her wizard teachers telling her not to. Ariane generally uses logic and reason to solve problems and may be described as naive at times.
Ozan is a bold and brave thief who tells exaggerated stories of "his" adventures, which no one usually believes. Born in Al Kharid and raised in the streets of Varrock, he is a skilled ranger and an agile person. Many say he is more obsessed with fame than doing what is right. Ozan usually follows his emotions, which quite often brings him into trouble.
Sir Owen (originally "Sir Ewain") is a strong melee warrior and is an elite member of the White Knights and Temple Knights. A devout Saradominist, he focuses on doing what's right, and scorns stealing and criminal activity. He believes Saradomin grants approval of his actions, and will do anything to achieve them for Saradomin. Much like Saradomin himself, he is benevolent, but will go very far to succeed in his goals, his faith being great and undoubted.
Xenia was a retired adventurer who was part of a previous generation of heroes, and has adventured with many other famous adventurers, such as Radimus Erkle, Harrallak, Shanomi, and the Wise Old Man. She acts as a mentor to the other heroes. She and Radimus founded the Heroes', Champions', and Legends' guilds. She has travelled to the Eastern Lands, but sworn to secrecy about it. She was killed by Ariane during the Heart of Stone quest. After her death, she aided the player, Death, and Icthlarin in defeating Nomad for good.
Linza is mainly interested in things related to Smithing or other handicrafts. She is always interested to learn of new techniques or materials for Smithing. She does not like machines with moving parts, preferring the simplicity of a balanced sword. A primary drive for her is creating 'the perfect sword' and things similar. After Kindred Spirits, she becomes Linza the Disgraced and joins the other seven Barrows wights at the Barrows.
The Raptor is a mysterious warrior who is very adept at combat, but not very talkative. He appears to be rather reluctant to cooperate with others and generally seems willing to kill anything that gets in his way.
He can be found in the quest Song from the Depths, slaying chaos dwarves at the Chaos Dwarf Battlefield, dying to brutal green dragons in the Ancient Cavern, or fighting lesser demons in the Karamja Volcano, as well as fighting on the Khazard Battlefield. He cares only about fighting and proving himself in combat regardless of what he is fighting, or why.
The Player (World Guardian)Edit
The player character is a skilled adventurer of all sorts and can be learned in any of the skill sets. The player is appointed by a dying Guthix to be a World Guardian at the end of The World Wakes quest.
There were quests scheduled to come out mid-late 2010 featuring the Signature Heroes as ally characters. However, they were delayed or cancelled. Quests featuring each of the Heroes have since been released.
The loading screen that appears before the login screen used to have pictures of Ozan and of Ariane. Ozan was pictured jumping a long jump in the Temple of Light, and Ariane was pictured fighting an army of undead with magic.
- Ozan, Ariane and Sir Owen feature in the background of the Runescape homepage that was released with the Dungeoneering Skill (in which they are shown Dungeoneering) one and a half months before the development diary was released.
- Xenia was the first Signature Hero to appear in game (not counting the player) and the first Signature Hero that players could interact with.
- Korasi and Zanik were briefly considered as candidates for Signature Heroes, but were rejected as both were too tied into their own storylines.
- A trailer on the RuneScape Youtube channel shows the signatures heroes, Ozan, Ariane and Sir Owen fighting a horde of undead. http://www.youtube.com/watch?v=CdRUcFqL2lQ
