I've ported into Butcherblock Mountains hundreds of times but this only happened once. I cast the port spell and when I arrive in Butcherblock I'm waaaaay up in the sky about as high as you can be. Then I start falling, real fast. BAM! I die.
I port back to find my corpse and then consider whether I'll just loot it and eat the death or try to convince a cleric to come here and rez me. (This was long before druids got rez spells and even before merc clerics.) Well, I can't locate my corpse. I looked all around the druid ring and even in nearby areas no corpse. I type /target sippin's corpse and got a response like "out of range." Oops. My corpse is beneath the world!
So I /petitioned. Here's one of the great things about the OLD game. In about 5 minutes a GM shows up and I explain what happened. He smiled, gave me some milk and cookies (I think... they always did that back then) and advised me to wait a few minutes he'd bring my corpse up from the Norrath Netherworld. Sure enough, he did, then gave me a 100% rez, apologized for the undeserved death and wished me Happy Hunting.
