How Did Pyrriah Know About the Lost Continent 

I largely agree it is likely the pass of clearsight (the string of islands clearsight mapped out) was a hive of activity from lets say 500-c.1500AS though something caused contact to end around c.1500-2000AS so that a millennia to a millienia and a half later pyrhia pentala knew of each other but it was essentially like our ancient legends even by c3000AS so that in 5012AS the discovery it was real was a shock for both continents even if each existed in the others myths

Yes you can post it. You don't have to ask me if you can because I'm not the only person who has thought of this theory.

Oh sorry I meant I might post it I think you misread 😅
