Wally

Wally in the opening cutscene from Demon Slayer

Wally the Demon Slayer is one of Varrock's most famous heroes. When the powerful demon Delrith attempted to destroy the city, Wally narrowly managed to defeat him with the sword Silverlight in the 19th year of the Fifth Age, 150 years ago. He died sometime after but his greatness has never been forgotten.

Sir Prysin is his great grandson and is currently in possession of Silverlight.

Trivia

• Wally's helmet, which he is said to have worn when he battled Delrith, is displayed at the Outpost near Ardougne after completion of the Making History quest. During Demon Slayer, when a cutscene shows Wally defeat Delrith, he is not wearing a helmet. This is most likely just an accident by Jagex, or because if he had a helmet on, the incantation he had to say wouldn't be heard clearly. It is also possible that it is a reference to how much of Runescape's history is popularly known in an incorrect form (for instance, that Saradomin created Gielinor and that gnomes and humans both descended from the same relative, but gnomes came first), and that the helmet being Wally's is only a legend that was attached, for whatever reason, to the helmet at some point in the past, whether true or not.
• Originally, Wally did not appear in any cutscenes and was only mentioned by Gypsy Aris and Sir Prysin.
• For some reason, Wally appears bald in the cutscene, but is shown with hair in his picture slaying Delrith in the Lores article, Eulogy for a Forgotten Hero(which was released after the cutscene update).
• Although Wally is visible in a cutscene during the Demon Slayer quest, he has no examine option.
• If you look carefully you'll notice that Wally's beard is different from his face upclose to his beard in character form.
• If the player is quick enough and chats, it will appear above Wally, indicating that Wally is just a player skin. The same is the case for the Wise Old Man during Swan Song.
• Wally wears Silverlight as a two-handed weapon, unlike the player.
