In order to be able to finish this quest you need to have done all quests in a line that starts with Suspicious Activity. The last few quests in that line is to kill the names where you get the trinket's for this quest. This step is not necessary, the quest can be started by killing the Animator and looting the trinket. It can be undertaken by any player regardless of alignment
You will need to have completed Bark Like a Gnoll to gain the Gnollish language and speak to an Elder Sabertooth Spirit at the end of the quest.
You must be good or neutral alignment to do the Suspicious Activity line - evil characters can ignore this quest line.
Once these are all collected, you need to go to the Stone of Graw (located within the underwater cave ( -1022, -47, 1178 ) /waypoint -1022, -47, 1178 which is an alternate entrance to Blackburrow. ( -1092, -33, 1074 ) /waypoint -1092, -33, 1074
Note: You must still have the trinkets in order for the Stone of Graw to advance your quest.
I should speak with the spirit at the Stone of Graw to see if I am yet able to receive its blessing.
