The lord of the castle can ride a wyvern freely throughout the sky.

Wyverns can only be ridden by speaking with the Wyvern Manager at the uppermost floors of the castle.

To ride a wyvern, one must be riding a strider when speaking to the Wyvern Manager. B-grade crystals are required.

Wyverns, like other pets, need to be continuously fed with wyvern food. If they are not fed, they will be forcibly unsummoned and players will be returned to the closest village.

While riding a wyvern, you may not attack any monsters, but you may use the wyvern's special breath attack skill to attack other players.

You cannot pick up items while astride a wyvern, and players cannot use skills.

When /dismount is used, wyverns will promptly disappear. When the wyvern is unsummoned in mid-air, falling damage can be applied - so beware! When riding wyverns into special regions, like the top floor of the Tower of Insolence, where one cannot go under normal circumstances, dismounting is not allowed.

If the castle lord changes while the player is riding the wyvern, the former castle lord will be forcibly unmounted.
