Metalynx of old were feared in battle not only for their scimitar tails, but also for another ability: to call rain to heal itself, as their faces were clad in fearsome thorns that directed the rain into their mouths. As time passed, however, they developed a need to protect their kittens, and kept developing stronger and stronger armor, but eventually lost their face spikes. As a result, they found that their protective drive had come with a terrible cost: they were now twice as vulnerable to the heat and could no longer rely on the rain to heal themselves, only as a shoddy defense against their own mistakes.
