Here is my first objective marker for the eldar: a Wraithlord sword stuck into stone, like a giant future elven excalibur.
I didn´t thought about some history to fit this objective marker or make some planning and designing of it, I jus saw the wraithsword while cutting the wraithlords out their sprues and started to play with the spare bits, added a bit of a bright lance to the bottom of the blade and a bit of a heavy weapon to the bottom of the latter, and with a spare bit of polystyrene and a spare monster base it came together.
I´m still thinking what to do in the marker to make it "come to life" and add a bit more of character to it, I will paint the "rune" in the blade and try to add a directional source of light to the rock from the sword.
P.D.: I also played with the glue and the sand in the base, that is why there are "waves" in it.
