Again these are some of the original 40k models. I am really pleased with how these have came up and that they are finally finished after eons in psychic status.

A Wraithlord, also called an Iron Knight, Wraith-giant and by the Imperium an Eldar Dreadnought, is a Craftworld Aeldari robotic combat walker known as a Ghost Warrior that contains no living pilot; rather, it is merely a robotic shell, a repository of the animating soul of a dead Asuryani hero. Wraithlords are graceful but mighty giants that dwarf their smaller Wraithguard Ghost Warrior cousins.

These large constructs are extremely precious to their Aeldari craftworlds and have a supernatural toughness due to being made from the psychically-active substance called wraithbone.

Summoned into being by the necromantic processes of the Asuryani Spiritseers, only a true hero of the Aeldari people has psychic power enough to animate the gigantic wraithbone shell of a Wraithlord.

History abounds with tales of enormous statues magically coming to life in defence of primeval crypts or to avenge ancient wrongs. The image of these towering constructs shuddering into animation is ingrained in the Human psyche, and explains the visceral reaction most Humans have when first encountering the Wraithlords. 40k Fandom

The bases are from Back 2 Base-ix

Although I do not play 40k much these days I really do like the older GW metal models, and the Eldar do have some of their very best.
