Speak with Anda once again ( 1031, 164, -470 ) /waypoint 1031, 164, -470 she'll tell you where abouts the bounty hunter can be found. You can find the bounty hunter in black at Varis. This is Colonel Leevan ( -430, 119, -361 ) /waypoint -430, 119, -361.
Speak with Colonel Leevan; the update is timed and you have to fight him. Keep talking... and make a pact. Talk with him until he stops, fight and "kill" him, then talk with him again.
Find the Odd Bluish drolvarg that you saw leaving the Gra'al Shul Temple and talk to him. (This is Indigo at ( -1665, 85, -597 ) /waypoint -1665, 85, -597.) North of the Kunzar's Edge Bird Station, and east of the Fens Sokokar Station.
Click on the chest at ( 1240, 427, -1170 ) /waypoint 1240, 427, -1170. This is inside the tower at Charnax, which is in the Icebound Pass.
The chest is locked! Find the way to open chest. To get a hint and progress the quest, inspect the clipboard to the right of the entrance to the tower on the inside wall ( 1242, 427, -1170 ) /waypoint 1242, 427, -1170.
The clipboard tells you to find the body of Warlord Fardax in the Icebound Pass. He holds the Key of Charnax. The key is found at location ( 1327, 385, -780 ) /waypoint 1327, 385, -780 in the yeti caves. It spawns on the ground, behind a rock. There is no body to be found, just the key. Maybe the yeti ate him? (Frostcoat might be sitting here).
Locate the second magic chest inside the Tower of Westin Rouk near the sarnak mine overlooking the Stone Wood. ( 825, 412, -1592 ) /waypoint 825, 412, -1592 This chest is also locked.
Go to the base of the tower and talk to Seepay the frog. ( 848, 383, -1543 ) /waypoint 848, 383, -1543
Go to the Ryjesium Mines and get the spider gem updates from the foremen. ( 514, 351, -1581 ) /waypoint 514, 351, -1581 This area is reached from the top of the tower -- follow the stairs all the way up, and then follow mine cart tracks and turn left at the fork.
Go to the Arbor Giants' Fort, Karatun Hold, and steal the coin bladder. It can be at three alternate locations: either at Arbor King Zamont's feet ( 784, 90, -2249 ) /waypoint 784, 90, -2249 or a few feet away, on the table ( 822, 89, -2234 ) /waypoint 822, 89, -2234. It looks like a bag of flour and you have to get quite close to see it. It may also be in a nearby shed at ( 923, 77, -2305 ) /waypoint 923, 77, -2305, on the table. Note that the place crawls with wandering giants that see through invisibility.
Excavate sarnak petroglyphs. These harvested items are in the Wurm Caverns in the area called Den of the Broodmother in the back left corner, ( 1718, 233, -2049 ) /waypoint 1718, 233, -2049. They appear three to five at a time, with a one to two minute respawn. After harvesting all that you need, return to the tower and speak with the Historian Holdak. He will give you Tablet of the Wizard.
Go to the Towers of Sel'Nok and find the next chest. The chest is located at ( 2274, 197, -2622 ) /waypoint 2274, 197, -2622.
NOTE: The Di'Zokian language is NOT given to you when you turn in "A Mysterious Red Tome". You must then speak with Emissary Glochk, found at the Monolith of Woe ( 1125, 151, -1899 ) /waypoint 1125, 151, -1899 and complete 2 quests. Glochk will then teach you the basics of Di'Zokian.
Once you completed Emissary Glochk's quests go to the tower across the road from the tower where you found the locked chest. Read the note behind the The Vault of Sel'Nok, ( 2082, 188, -2549 ) /waypoint 2082, 188, -2549.
Speak the words, and kill him to get the disc needed to open the chest.
Kill Sel'Nok infiltrators nearby to get the gem updates, then open the chest to get the last tablet, Tablet of the Ruler.
Return to Indigo ( -1665, 85, -597 ) /waypoint -1665, 85, -597. Talk to him, then kill him within a TIMED ring event (20 minutes) to receive Music Puzzle Box.
Indigo may not be spawned if recently killed. His respawn time is 20 minutes.
To start the ring event talk to one of the hooligans (only one of the front four are hail'able - random/different each time)
There is a first wave of defenders (roughly level 70 double down) followed by two 68 single down defenders. They both spawn at the same time, so if you open with an AE, you'll get two groups.
Lastly is Indigo. He is a level 69 ^ mob. You must kill him before he reaches the road. Be careful, he tries runs off the cliff behind you when he becomes attackable. If you hit him quickly enough, he'll turn back to attack in return instead of running for the road.
Return to Colonel Leevan ( -430, 119, -361 ) /waypoint -430, 119, -361. Speak with him for your reward.
He lastly mentions a "bounty posted at the tower just beyond the pass into the Fens" which might interest a bounty hunter such as yourself... (in front of the Rhinos on the outside of the tower)
