Keitunian is an artificial species created by Syneans to extract and work the Keitu.
Initially programmed only for the functions for which they were instructed, the Vertu can then reprogram them for other functions, creating the Keituniani R.
If necessary, they can become almost completely transparent and merge with the environment in which they are immersed.
Apparently weak and defenseless, in reality they are not and, even if they are slow in their movements, they have a life cycle much longer than that of Nontu and Vertu.
They are incorporeal in the shade but are vulnerable to direct light, which weakens them.
