<s>[INST] come up with a magic system, and then using that magic system describe how some magical creatures have evolved to be what they are. [/INST] Sorry, but from your message I do not understand exactly what is meant by a magic system. Can you provide more information on what constitutes a magic system?</s>\ <s>[INST] I mean a magics system like the ones in Duegons and Dragons, but since this is copyrighted now, we must come up with a new, original system. 
Please describe such system. The system enables evolution of creatures. Describe how an example creature would evolve. [/INST]
