Each collar is bonded to a specific ring , and only works with said ring .

Once attuned this ring collar allows voluntary telepathic communication and understanding between rider and mount. It also allows communication attempts between other bearers. The other bearers (of mounts and collars) may shrug off attempts at communication.

How the Wyvern wearing this collar reacts to wearing it depends greatly upon it's treatment. It s a metaphorical bridle, not a ring of command. The Collar wearing Wyvern will obey, to a point. If the relationship begins "Well" the Wyvern begins with 10 points of Obedience. Each Order given the Wyvern disagrees with, reduces this by -1. Each Order given the Wyvern agrees with, or each time the Wyvern feels Indulged, gives a +! to the Obedience total.

How much Obedience the Wyvern begins with is a minimum of 1 and a maximum of 10, dispensed at the DM's discretion.

While still under the influence of Obedience, the Wyvern is docile and obedient... If the effect is broken... Don't call the manufacturer, or, well... don't have your kin try to.

The Wyvern also improves with it's rider, gaining HP max as the rider gains hp max

The bearing Wyvern also gains the independent ability to speak to any other bearers ( both of the Collar and Ring)

This Collar can "point" to it's corresponding Ring  within one mile;
