Dark runes

As I moved towards the Ironspan my feeling started to warn me. I felt uneased, like I should turn back and forget whatever may be in there. However I refuse... And I did not seem to be the only one suspisious about the place.
As I neared the secret path into the span I was greeted by two old friends. Noora and Valio of the Lossoth outpost in Jä-Rannit just outside Reodh Fuil. They had seen Angmarim move deeper into their lands and decided to go investigate themselves.
We decided to go together. The tree of us sneaked out way inside using the secret passage. We took out a guard or two along its way untill we were far behind the enemy's line inside the stronghold.
There..... Far inside the stronghold we found a weird looking runestone. It felt dreadful and evil. 
Though all my effords to read the runes and find knowladge on this stone, I had nothing to return with. 
As we heared a loud bell we knew that the Angmarim would be comming. We had no more time to investigate...
We ran back to Jä-Rannit as fast as we could. For now we can't do much. But we must not let the Angmarim travel deeper into the lands.

I will return here to finish this. But not now... I must now head to Sûri-Kylä to warn the Chieftain.
