Grotas species (Patreon)

 About the last one drawing: besides 'civilized' grotases you can find persons who renounced from technologies, and live in the wild. They said, that 'technologies - it's not our natural way of development', but, in the same time, some of them are raiders and don't neglect to use weapons and other 'civilized' stuff. Also they have more better immunity, than the first ones.
