The 4 NPCs you'll need to get tasks from are:

In Dragonscale:

Crystallos Group Access NPCs (need for raids):
Tonas; 2205, -45, 184; - Clear Crystal
Vesiss; 1862, 2277, 127; - Glowing Crystal
Jashy; 171, 372, 171; - Cloudy Crystal
Aring; -17, 1813, 177; - Light Blue Crystal

I'll get layer 3 maps up with the points needed, but:

Tonas - Crystal in the NW cave in Dragonscale (Can invis to)
Vesiss - Crystal in the Eastern cave on the ramp down into Loping Plains, lower of the two caves (Can invis to)
Add this line to Loping Plains Map:

/code:

P 2713.2893, 99.2386, 330.5019, 0, 127, 0, 2, Vesiss_groundspawn_-_lower_level_of_ramp




Jashy - Crystal in the Crypt in Hills of Shade (Underneath where we fought the big guy, though I'll have points on the map for it). Rogue SoS/Monk/DA train required, if you want to get it solo.
Aring - Crystal in the furtherest, lowest part of Meldrath's Mansion. There is a way into this zone without a key (and it actually takes you very near this crystal), BUT Rogues can't get to it as almost everything at that level sees SoS. DA train or 2 groups the way to do it.

Crystals are CONTAINERS. Make sure you have room.

Crystals have a 30 second respawn.

After you have the Crystal, you need to have at least 1 group and you need to kill specific golems on the way to Crystallos, which is off Dragonscale. This will also be on the map. You'll all be doing this several times, so don't be annoying about it.

What happens after you've killed the golems, I'm actually not sure, but we'll get to that when we get to that.

Additional stuff:

DRAGONSCALE LOCATION POINTS:

Place these at the end of one of your dragonscale_#.txt in the /maps folder.

Alright

Once you have gottin the 4 groundspawns and have re-hailed to update you quest you will need to kill 10 spawned golems.

Quest should now say "Our Lost Brother- A Clear Crystal, A Cloudy Crystal, A Glowing Crystal, A Light Blue Crystal"

By clear ing the named drake and area trash you are ready to spawn the golem. All you need to do is get close to the pool. Each area will spawn a Golem., and some will have adds spawned. Each golem will drop 6 quest pc's. Those are as follows
Essence of Life
Essence of Decay
Essence or Water
Essence of Thunder
Essence of Arcana
Essence of Iceicles
Essence of Fire
Essence of Rage
Essence of Mana
Essence of Sadness

A Clear Crystal Base has 2 slots and needs (Life, Decay)
A Cloudy Crystal Base has 3 slots and needs (Water, Thunder, Arcana)
A Glowing Crystal Base has 2 slots and needs (Iceicles, Fire)
A Light Blue Crystal Base has 3 slots and needs (Rage, Mana, Sadness)

After you have kill these events and looted the pc's and combined them you will have to go and hail Tonas, Vesis, Aring, Jashy. After that you will need to go find Laiyken. He will give you a 4 sloted case. You need to put in the 4 crystals you had just made and hit combine.

Then you will have a Prismatic Crystal Charm This means you are flaged for Crystalos. The quest continues with a few locates in Crystalos then sends to back to Laiyken and he will send you to Meldrath to locate the Lost Crystal of Kerafym.
This is the second to last line in the quest and also is where I am currently at. So once i locate this crystal (am thinking its a drop) will post further
