Spirit Guide

From WoWWiki

Spirit guides are factional Spirit Healers in battlegrounds that resurrect players who have fallen in battle. They take the appearance of their own faction. Unlike normal spirit healers, they resurrect players with full health and mana and no penalty every 30 seconds. In addition, they resurrect pets or minions of the fallen player (if they had one when they died). In battlegrounds where graveyards can be captured, players' ghosts are teleported to the nearest spirit guide if their current spirit guide cannot complete the resurrection before the graveyard is captured.
