PaperCups,
In the future, you can always summon your corpse in the Guild Lobby. The Guild Lobby is a zone off the Plane of Knowledge. I think you should access to it with the version of the game that you bought (if I remember your other posts correctly). On the east and west side of the Guild Lobby there are corpse summoning NPC. Puchase the required item from the merchants in the Lobby. I don't know the name of the item you'll need at level 13. Hand this item to the corpse summoner and your corpse will appear right in front of the summoner. Very handy if you ever "lose" your corpse.
Also, as a necromancer, you have a low level spell called locate corpse. First, while in the Field of Bone, type (or hotkey) the command /corpse. If your corpse is in this zone it will say that you are too far away. If your corpse is not in this zone it will say so. At that point, just head to the neighboring zones, and type /corpse again. Once you find the zone that your corpse is located, target yourself and cast locate corpse. It will point you in the direction (straigh line) of your corpse. Run that direction some then recast, it will point you the correct direction if you veered off course. Repeat until you find your corpse.
Good luck!
