DISCLAIMER: Your Steps and Tasks may be different
Go to the Albion Runner in Camelot (he is located near the green bit near the church and the exit from the round table area toward the guild of shadows), speak to him he and will tell you that your assistance is needed and that the journey will be difficult and long. He will tell you that you will need to investigate the disappearance of the city of Lyonesse etc.... your journey will take you past CW, you will need to tell him "Caer Witrin" and he will tell you to seek a named guard in Cornwall station staying upstairs called Edmond.
After speaking to him he will tell you what your mission is in whole then
your steps will kick in. Go kill 2 undead farmers in Lyonesse. Get on the road follow it until in Lyonesse, be careful of Lesser Telemons near standing stones, you can't miss them in Lyonesse. The road will go into the water, go to the left of the shore line and be careful of monsters in the water. Get back on the road as soon as it comes out and watch out for Telemons red at lvl 38 (cleric). To get past them use a group to take one out or run dead centre of standing stones. Once on road your safe, follow the road until there is a small puddle on your right. Next to the large expanse of water try to use the same tactic to get passed the Telemons again, be careful of Moor Liches. There should be a house in the water and a house on the top of hill (this is the pygmy goblins). Follow the shore line passed the house you then will start to encounter Shepherds and Farmers these were yellow and orange to me at 35 yellow and blue at 37 kill your 2 farmers.
Then it will say find the ruined temple and locate the guards (names I can not remember). Then follow the shore until you see another expanse of water ahead of you, follow its shore line left. On your left at this point you will see some ruins, then some guards. Walk slow toward one until a message flashes in your box and your quest step changes. Do not try to take them h2h they are hard....
Head back to Edmond in Cornwall Station... you will receive 70+ sliver and some exp. (about 5%).
The next part of the quest kicks in about a monster ambushing his men on the road side he needs you to take care of a monster Moor Bogey called Yog. Yog is located near the hill that has the entrance to the Catacombs. Leave the station and head along the road where is splits of to the left head at 45% to this road toward the catacombs there is a tree line to the left just level with the tree line you should encounter him. His exact location was 44k, 40k (also found at loc=40738 36939, 11h 6m 30s game time). He was yellow at 37 and easy to solo as other Moor Bogies. They will only add if your within range after killing him. Look in your pack nice weapon: Yog's Iron Fist, a proc weapon yellow at 35. Head back to station for another 3/5% experience and 5 silver (not sure on the silver). Quest completed fairly easy once said monsters are located.
(this quest was done with a lvl 37 cleric on the Prydwen Euro server)
