Arrav was a legendary hero in the 4th age who defended Avrrocka (later Varrock) from a powerful necromancer named Zemouregal. Unfortunately, he ended up having to sacrifice himself to save the city, but he was honored with a statute in the Heroes’ Guild, his shield on display in the Varrock museum, and his battle axe on display in the Outpost. Or at least it will be once you complete the quest “Making History” and go through rebuilding it. He is very well known and loved throughout the city for his actions, and he was also known as Arrav of Avarrocka, Curse of Goblins, Child of Sun and Moon, and the Hunter of the White Stag. It’s a pretty long list of titles and your adventurer might want to live up to that someday and get some titles of their own.
