Titles - The RuneScape Wiki

Titles are honorifics, accolades, ranks, and other descriptions that modify a player's name as either a prefix or a suffix. Titles will appear with a player's name in public chat, when the player is right-clicked, on the forums, and on the player's adventurer's log. Titles are accessed and changed through the Customisation Interface under the "Titles" tab. Titles may be obtained in game or from Solomon's General Store. A number of titles do not appear in the interface until they are unlocked. The first titles in game were the Mobilising Armies military ranks, released on 8 July 2009.
