Random Riddle: Rampant Children

Some men struggle against me, others cheer my victory.
My allies’ work is often covert.
My children run rampant.
Spreading my influence over mountains and valleys.
My foes are crushed without prejudice.
Belenus can be a friend or foe.
Chac can have disastrous effects on my travels.
