Bunny dragons develop what is commonly referred to as a 'steel trap bond' with their bondmate. What this means is that the dragon may not, at any time, have more than one bondmate. And the bondmate, at any time ever, may not share a bond or a sympathetic empathic link with another creature.
What the dragons feel through a bond is access to their bondmate's memories, their feelings, their passions. Anything the bondmate feels, that's what the dragon feels. Pain, heartache, joy and laughter. And similarly for the bondmate. They become extensions of each other, compensating and commiserating and sharing and living. These shared feelings can be blocked out by either one on the receiving end at any time, so if one's bondmate is being particularly giddy while one needs to difuse a bomb in three seconds or less, one can concentrate. However, when the floodgates open again, be ready, because the explosion of emotion from some of the more envigorated colors will be staggering.
Bunny dragons are very very protective of their bondmates, though the bond is also fragile. If either of the bond dies at any time, so too does its bondmate. Warriors and soldiers of fortune are at once encouraged and discouraged from taking BDs as a bond, for they lend the fighter their strength, but also their cowardice and their fragility. On the other hand, dragons who have taken mortal bonds live for centuries, and so, too, do their bondmates, their lives stretching out, their bodies ceasing to age once they have willed it to do so.
These dragons, however, are far from indestructable.
Bunny dragons are psychically sensative creatures, and having to 'share' a bond with more than one creature causes them to endure an excessive amount of stress, often to the point of dying within hours of the second bond's establishment.
The effects of a broad-spectrum empath or hive-mind creature bonding a dragon has not been tested, though it is likely that this, too, will create too much stress for the dragon to survive, and at best that the dragon will be listless and depressed. Narrow-spectrum empaths, those who can influence but not receive emotions from others, are sometimes healthy bonds of dragons, though these are often lucky crap-shoots.
Abandoned dragons do not have as tight a bonding as non-abandoned dragons, though they still will not tolerate a second bonding on any party's part. The exception to this is bond-transfers, which are detailed in the Life section of the website.
It is the wish of most dragons, somewhere deep in their hearts, to one day break free of the compulsive bonds to creatures, and to one day be able to exist, if they so choose, alone. At this point in their existance, however, no means have yet been presented.
