Conversation is of little interest to a wyvern, as the creature typically speaks only to taunt its prey, issue territorial claims, or demand tribute. Even so, many wyverns enjoy grim humor and tales of violent acts, particularly if those acts were committed by the storyteller. A wyvern properly appeased with meat, entertainment, and treasure sometimes agrees to provide assistance ranging from giving directions to serving as a mount for a powerful humanoid. However, these arrangements rarely last more than a few weeks before the wyvern's pride, malice, or insolence inspires it to flee or even betray its allies. Only the truly cruel can cow a wyvern into servitude for an extended period, as most wyverns are so self-interested that they go out of their way to avoid helping others.
