Legacy of Lofacham

I have also heard the rumors about Rophacham. But those rumors did not originate here. Some Travelers passing through spread them. They asked me, just like you did, 'We heard Rophacham lives here, is that true?' I may have been alive a long time, but I'm not quite 100 yet. There is no way I could know anything about Rophacham. However, I once heard there's an Orc Soldier buried somewhere in the forest.
But I'm not sure where it is. I will try to find out but I will need your help. Kill <HFFFA7272>24 Centaur Airbornes<HFFFFFFFF> in the <HFFFA7272>North of the Prince's Hunting Field<HFFFFFFFF>, which is where I will go. That's the only way to find the truth.

Don't expect to find anything specific because it is just a rumor. Kill <HFFFA7272>24 Centaur Airbornes<HFFFFFFFF> in the <HFFFA7272>North of the Prince's Hunting Field<HFFFFFFFF>.

I found a square stone, but I couldn't read what was written on it. Magic moss kept preventing me. How can I read it? I need to figure this out.
