Dialogue
 * "Your earlier heroics enabled us to reestablish our hold on Arborstone, the sacred cathedral of the zu Heltzers. Withing its depths are great stores of magical amber. Unfortunately, as a side effect of the wardens have been drawn to the area in droves...and our defenses have been overrrun! My nephew, Terrik, has been trapped inside. He is a talented stone singer, able to control and construct magical protectors, and I sent him in to summon stone guardians to help fend off the wardens. But despite his talents, I fear that he alone cannot win this fight. Please, help Terrik zu Heltzer and zu Heltzer Guardians defend Arborstone at all costs."

Walkthrough
Head out to Arborstone from Altrumm Ruins. Follow the wide corridor to where the ques star on the map is pointing. You will engage several Warden groups along the path. You cannot go straight to the mark on the map, instead you must climb the stairs on either side.

Beware that if you come too close to that mark from below, you will cause the assualt to begin which (by the time you go around and up the stairs) will mean Terrik's certain death. His death however has no consequence as you will still complete the quest successfully if you kill the Warden groups.

This is a difficult quest. There is a priest at the resurrection shrine who offers a blessing for 100 gold, this is worthwhile. You will be assaulting groups of Wardens larger and higher level than yours, and they will be sitting in a nest of spirits and traps. A direct assault is suicide. Assassins will find that a shadow step to the middle of the pack results in almost instant death.

Instead, try to lure the warriors out of their traps and attack them. Keep moving backward out of the Churning Earth that the Wardens of Earth cast. When three or four cast Churning Earth at once they can decimate your group in seconds. Rangers and mesmers should focus their interrupts on them. Once the Wardens of Earth have cast or lost their Churning Earth spells, assassins can shadow step to them and take them out.

This quest is difficult to do with henchmen, as they do not lure and disengage well. They will charge the pack of wardens and traps and die quickly. Best hope is to take out the casters first, even if it means dying and coming back to finish the fighters.
