How did we understand the Ancients fluently when we went to Elpis? When it's already established they speak an entirely different, incomprehensible-to-us language? I don't actually even remember how we understood the shades in Amaurot but I do recall they weren't literally speaking our tongue we just somehow understood what they were saying without actually understanding their language. Yet when we go to Elpis they just speak fluent modern-tongue?

I mean it's already bad enough the people of the first speak the exact same language as the source.
