Morgul wasn't what Gernet was talking about when he said he lacked direction. Although the god had been perhaps more hands-on than gods of Earth tended to be, he didn't direct the naga's life in a personal way. He'd appear in the clouds, make a big show, promise and threaten and lead, but there weren't many requirements. Keep up the sacrifices, destroy their enemies, and eventually they'd be able to take the light side from the thieving lamia and their bitch goddess.
But Gernet did worship his god, fervently and desperately, loyal in a way he wasn't to anyone else. The scars that marked his body were something that was done as a show of power over victims - not something that a naga would generally do to themselves. "My god may not be on this planet, but I know he's still there." Perhaps he wasn't able to sacrifice in the proper manner, but he still retained some of his original magic and that had been a gift from Morgul. About any king or emperor, Gernet would have agreed with the angel, but in his heart the naga didn't just follow Morgul because he was the most powerful. He wasn't quite aware of this, wouldn't be able to say why he did follow, but his devotion remained steady.
"I meant. I don't know who's at the top. I can't find my place." For over two hundred years the snake had been climbing a ladder. The most powerful would be at the top - you'd watch your back or die. It was a vicious, cruel world, and all he'd ever known. And now he was lost and adrift. "How do you find a direction when you don't even know where you stand?" In his distress, Gernet was forgetting that he was talking to someone not much more than a child. But it probably wouldn't have mattered much - talking to anyone so freely was strange.
