Edge of Eternity

This achievement is unlocked by completing a series of two side quests. First, complete "Biting the Hand" which is found in Tyr-Caelum by speaking with Frey. You will need to exit the city and get on your Nekaroo, then follow the quest markers to find Griff in the Jungle. Defeat a monster and return to the city to complete this quest. Then you can immediately accept and complete "Bare Necessities" which is also given by Frey. Simply head to the other side of town to speak to two NPCs, then return to Griff and choose who you take him to, the Orphanage or the Apprentice. This completes the quest and pops the achievement.
