There are 3 NPC's standing along ice wall near Starn Bearjumpers place. Talk with the human wizard Sulgar and he will tell you that he is looking for tartons wheel. (you must have good faction with beta neutral to get this quest). He gives you a glowing case and a tome of hints that spans all over the 3 continents. The case is to hold the spokes of the wheel and the tome gives you hints on where to find the pieces. Be aware that the case is a no rent item and will disappear when you log out, so don't put any rods in it until you are ready to give them to Sulgar.
You combine the pieces you find in the box and get The
Staff of the Wheel and The Star of Eyes
(a gem which casts unlimited identify spells). When you give these items to him,
he will give you the runes of frost and astral needed to research the ice comet
spell. (You then pray your research doesn't fail). There are 10 pieces that you
need scattered across the face of Norrath. The names of the 10 rods are: Azia,
Beza, Caza,
Dena, Ena,
Fana, Geza,
Heda, Izah,
Jaka. They are just called "a
rod", and identify as wizard only.
The locations are as follows:
Azia - On the ocean floor in Eruds Crossing past the zombie boat where the zombie sailors hang out. (location - neg 1162, pos 2340);
Beza - In the underwater cave in the Everfrost plains. It is in the "house" all the way back and right in the cave, where 3 dry bones guard it in the center of the room;
Caza - Lake Rathetear. Underneath the first island you see is an underwater tunnel leading to a stone tower. Its on the top floor of the tower. (You need enduring breath for this one);
Dena - Dagnor's Cauldron, right outside the entrance to Kedge Keep. If you face with your back to Kedge, it is directly diagonal left, in a corner - or you can swim straight out and down from Unrest;
Ena - Lower Guk in the Reanimated hand room. This one is the only one you need a group for, unless you're brave and kamakazi it. Warning, the floor is the same color as the rod in this room and it makes it very hard to find with the hand and the dar beating on you;
Fana - Oasis of Marr in the underwater tower next to the above ground tower, on the top floor;
Geza - Highhold Pass in the water near the waterfall closest to the Tiger Inn. There are 2 waterfalls there. The rod is in front of the one closest to the inn;
Heda - Qeynos Aqueducts, in the shark pit;
Izah - Neriak in the water in front of the bar called "the blind fish". The bar has 4 glass windows that are underwater, and the rod spawns right in front of those windows;
Jaka - Unrest in the water outside the right side of the house near where the the gnome spelunker is. Instead of going into the tunnel that leads to him, you go a little right of that entrance and there's a very short passage where you can find the rod.
