Rakanis looked at the mech from his perch. "Is this my quarry Inaeun?" He asked over comm link from with his helmet. "No but they are of similar design and Xanis doesn't care what happens to them. Its your choice to engage Exarch, may you strike swift and true." With that Rakanis warped from vantage point to another, closing distance on the mechs. Bigger than Tau Battlesuits and bigger the Eldar Wraithlords also but it would still be dwarfed if it stood beside even a scout titan of the Imperium. Rakanis remembered taking a Warhound Titan down from the inside with his brood but he wasn't sure if it was his memory or that of the suit he wore. Exarch armour from the Warp Spider aspect shrine was passed down from the previous Exarch after they die in battle but the unique Spirit Stone of the armour collected all the souls of those who have worn it. Rakanis was the name of his suit, his old name had been lost when he too became lost on "The Path of the Warrior" He was Warp Spider, the embodiment of war as a swift and crippling surgical strike.
OOC: Brief note on the Eldar physce. Eldar minds are highly attuned and experience every emotion at far stronger levels than humans do therefore they enact strict mental disipline upon themselves on whatever path they choose. An average Eldar learns to associate his warlike self with his armour becoming bloodthirsty and vicious with it on before returning to their controlled self after removing itself. To become "Lost" on the Path of the Warrior is to be unable to do that and be named Exarch or "Priest" of the aspect of war they represent. They serve as leaders and warriors on the battlefield but their inability to leave the path is seen a s cautionary tale by other Eldar.
Side Note: Brief? Yeah Right.
