As with Aphus Lassel and Marae Lassel, the Halaetan Islands also have their own series of XP quests.  This time, you will need to kill Eaters and take their jaws.  There are a total of 5 Eater Jaws available, but bear in mind that the Insatiable and Abhorrent Jaws are necessary steps in two other quests (Oswald's Skill Credit and Augmentation), so you may not want to use them for experience.  Each quest requires you to reach the deepest section of a dungeon and then remove an Eater's Jaw.

Quest 1:  Engorged Eater Jaw.  The lowest level Eater Jaw is located on a small island between Lotila and Traitor's Islands at 81.7N 71.2W and is restricted to levels 40+.  Note that this dungeon is also part of the Beer and Healing Machine quests, so you may want to plan accordingly.  The fastest way to the dungeon is to use a Silyun portal gem and then run south to the island.  The dungeon itself is filled with Eaters and Raving Fiun, so you will want to buff a slashing weapon, bane against physical and acid damage, and protect against all damage types.  Your goal in this dungeon is go make your way down as far as possible, so whenever you see a down ramp, go down it.  From the drop, head down the ramps until you come to a large ring-shaped room.  There is a down ramp on the north side of the central section of the ring.  Head down and take your first right.  You will come to several down ramps - take any you please.  Continue to the southwest and you will see a pair of ramps leading down.  The corridors lead to another ramp leading back to the NE.  Head down and you will see a pit in the middle of an L shaped room.  Jump down and you will land in the middle of a series of ring-shaped corridors.  Make your way as far as you can to the NE, NW, SE, or SW and you will head down another ramp.  Follow the corridor and you will find another ramp leading down.  From here on, the path is linear.  The final room has a small enclosed section with a portal in the middle of it.  Kill the Eaters here and you will receive a message telling you that you have dislocated the dead Eater's jaw.

Quest 2:  Ruined Empyrean Vault.  This Eater Jaw is restricted to characters 70+ and is located on Vanguard Island, south of the Fiun Outpost at 88.5N 59W.  The fastest way is to take the Fiun Outpost portal NNE of Sanamar around 77N 59W.  Unlike the previous dungeon, this dungeon only contains Voracious Eaters, so you can get away with only protecting against physical and acid damage.  This dungeon is more straightforward than the previous vault too.  From the drop, you will find two paths leading up to the E and W.  The easiest way is to hug the right wall, which will eventually take you into a large open room.  You can take either the E or W paths out of this room, which will lead you to another larger room, which is L shaped.  The far end of the L shaped room has a ramp leading up.  Continue heading up until you reach a small room with a pit in it.  From here on, the dungeon is linear.  Follow the corridors until you reach another pit.  Jump down and start killing.  The eaters in this final room drop their Jaws.

Quest 3:  Abhorrent Vault.  In addition to the XP reward, you can use this Jaw to begin Oswald's Skill Credit quest, so plan accordingly!  It is also the first located on the Isle of Ruin, at 88.5N 50.4W.  The fastest way to get to the Vault is to use a Silyun portal gem and then take the Plains of Ruin portal just NE of the town.  That portal drops you a couple degrees north of the dungeon.  Make sure you buff beforehand!  In addition to Eater Buffs, make sure to bane against cold damage and protect against everything.  More Info on the exact dungeon layout when I redo the quest...

Quest 4:  Ravenous Vault.  The fourth jaw can also be used to start Oswald's quest, but since this Jaw is worth more than double the XP of the Abhorrent Vault, there's no sense in wasting all that XP.  This vault is also located on the Isle of Ruin, so buff accordlingly.  Take the Plains of Ruin portal outside Silyun and run to 92.8N 48.9W.  There are several pits immediately in front of you from the drop - jump down the middle one (although the others go the same place in a bit more circuitous fashion).  You will land in the middle of a four-way intersection.  Pick a path and head down into a large ring-shaped room.  Fight your way around to the SW section of the ring and look for a path on the outer wall.  Head down the ramp and you will come to a Y intersection.  Pick a direction (N or S) and continue going that direction until you see a ramp leading down.  Once you find the ramp, the rest of the dungeon is linear.  Just follow the corridor until you reach the exit portal.  The Eaters that spawn around it drop their jaws.

Quest 5:  Insatiable Vault.  The fifth and final jaw has multiple uses!  You can use it for the experience, to start Oswald's quest, or to start the Augmentation quest.  Like the Ravenous jaw, it's a huge waste of XP to use this jaw to start Oswald's quest, but since you cannot use any other jaw to start the Augmentation quest, you may not want to cash this one in for XP if you are in the market for Augmentations.  This Vault is located on the north coast of the Isle of Ruin at 97.4N 48W - NOT inside the Shattered Outlands, fortunately.  In fact, it is quite simple to reach - either take the Plains of Ruin portal in Silyun or the Eastwatch portal in Sanamar and run along the coast around the Shattered Outlands.  You will arrive inside the dungeon on a ledge overlooking a pit.  Jump down and head either E or W and down a ramp.  Follow the corridor until you reach a four-way intersection (the right turn is a dead end and one of which is a ramp leading down).  Turn left and make another quick left heading down a ramp.  Continue down and you will find a mid-sized room with a pit in the middle - jump down!  You will land in the middle of a four-way intersection.  Take any path and head down until you see another ramp leading down.  You will arrive in the middle of a large, long room.  Pick either direction and you will come to a ramp at the far end.  Follow the ramps and you will come to another pit.  Jump down and you will be on the final level.  Kill the Eaters here and wait for the special message.

Rewards:  Take your Jaws to Westwatch and give them to Clemenza.  He will give you:
