Planar Undead: The Heroic Dead of Ysgard

Ysgard is a plane of the joy of battle - great heroes from all over the Multiverse come here, either when they die, or make it here still living to join the never-ending battles that take place here. It is a place of glory, honourable combat, and great heroes, both living and dead.

Sometimes, this never-ending battle can have strange effects on those who fall. The Plane has a slight bias towards Positive Energy - even the direst injuries are healed with great speed, and those who die are simply reconstituted the morning after their death (as if under the effects of a True Ressurection spell). Those who die many, many times may find themselves returning as one of the Heroic Dead - a strange form of Undeath, bestowed by the Plane to those who have proved their valour and glory time and time again.

They appear as themselves, wearing the armour and weapons they used in life (and still just as skilled, too), though they posess a shining, radiant quality. They appear "more" - they are taller, faster, more muscular, a shining example of their species. Their voices echo with power, and their will is unbreakable.

Consider this a "template", to apply to any humanoid (and a few distinctly less so), though other creatures like Dragons might also qualify, if they have proved themselves worthy.

AC - 18, regardless of armour
HD/HP - 8HD/Max HP per die (or more, if the base creature posesses more HD)
Attacks - 2, Favoured Weapon, +4 to hit
Alignment - CG
Special Attacks - the Heroic Dead can exude Positive Energy to Turn Undead as a Cleric of their HD. The Heroic Dead are also resistant to the level draining effects of other Undead, though other Negative Energy attacks may harm them as normal. Heroic Undead also have all other Undead qualities (immune to Charm and Illusion spells, etc).
