I would suggest a few changes:
"Maharana Bheem Singh, a well-known ancient king, ruled this area like a ferocious lion, but today he's gone, while his lands and wealth endure. This proves that power and influence are temporary. Only legacy remains. By the way, les me sit on this chair, where he used to spend his time, so that I can feel like a king myself.
Nevertheless I am not a native, so check with one if possible.
