Anrakyr

Anrakyr the Traveller is a Necron Overlord who woke with his mind intact and then walked away from his own crownworld to go wake everyone else's. Pyrrhia lost a ruler. The dynasty-less crusade gained one. He taxes every tomb he saves for troops and guns, and he does not wait for a phaeron's permission to do it.

Some Necrons call him a noble restorer of the old empire. Others call him a brigand with a warscythe and no master. The Pyrrhian Eternals do not care about the debate. They fire.

He can turn an enemy's guns around for a moment, which is a very Necron way of asking a world whose side it is on.
