Ok in Hellfire theres a Horde qust to escort a Blood Elf out of the 'Den of Haal'esh'
However Alliance can kill this Blood Elf while she's still in her cage. She just walks right through it when you attack her.
She also has a respawn timer of 1-3 seconds, not sure why but sometimes its instant others theres a 2-3 seconds delay.
Anyway its great to skill up your Unarmed / other weapons as she's constantly respawning, level 62 so fairly high level and in a deserted place.
