Murmigon and Gladiagon

Murmigon: It glides on small wind currents from tree to tree. Its membranes absorb sunlight which is its source of fire. It cannot create its own flames.

Gladiagon: Like its previous form, it cannot create its own flames. This one has to swallow charcoal that's used as combustion. It was not created in the labs and was long ago used for aerial jousting.
