There are five basic secret languages spoken throughout the Old World. A character with this skill can speak one of them:
| Battle | Certain Warriors can speak the secret Battle Tongue, a clipped, shortened, and otherwise unintelligible version of Old Worlder used mostly for giving commands during battles. The Battle Tongue can be spoken twice as quickly as any other language. |
| Ranger | Ranger characters can speak the secret Ranger Tongue, an old traditional language of the woods passed on from father to son and occasionally taught to favoured individuals. |
| Thieves' | Certain Rogues can speak the secret Thieves' Tongue. The Thieves' Tongue is unusual in that it consists of inflection and gesture only and can be spoken over another language. So, a character might say 'Good day to you, sir' in Old Worlder whilst winking thrice and picking his nose, but at the same time be saying 'Meet me at five o'clock in the usual place' through those gestures to someone who can understand the Thieves' Tongue. |
| Classical | Many Academics can speak Classical Old Worlder, a dead language akin to Latin or Greek in our own world. It is used in many academic and religious texts. |
| Guilder | This is the secret and powerful tongue taught to human Guildsmen. It is not generally used at all, except in the most secret and powerful of Guild rituals. The language - which varies from Guild to Guild - will never be revealed to non-Guild members. |
