Bogatstvo

You walk alongside a winding river, the land in the surrounding area is completely drenched. You spot an eery forest in the distance, and change direction to head into it. You spot a glowing yellow shape amongst the dreary woods, and as you approach it becomes clear that the shape is a manticore. The manticore sits with Nirah and a small manticore cub as he talks to a couple lionesses. They nod towards you and begin to walk off as he turns to look at you.
"Well I don't see many lions pass through here anymore! I'm Bogatstvo, and you are?"
You introduce yourself and explain you're here because you heard he was studding. He let's out a hearty chuckle and flops onto his side playfully.
"Oh yeah of course, I'll happily stud to any of your ladies!"
He groans slightly as he rises to his paws and leans into a long stretch. You realize quickly that he's getting quite on in age.
"Sorry about that old sport, I'm not quite as young as I used to be! Hey y'know this reminds me that I'll be retiring before too long, there's some thing named Каракатица that will be settling into my territory soon if you wish to wait. Calls itself a 'god' but I highly doubt that. In any case that's your choice."
What does he mean by that?
