So, considering that the successors of the divine 10 had stronger element than their masters (at least the principals, or most of the principals) (Cardes, Maxwell, Lucius and KM being the exceptions) I guess we can (a bit) safely assume that the water unit was the master of Kulyuk (fire), the fire unit was the master of Felice (earth), earth and thunder can be of the 2 left to know and light and dark will go with 2 of the exceptions I guess.
