loaded knife cuts like ice sharpened crystal water blade permafrost
cryovolcanic ore mind from the acid cave beyond the methane sea
enemies lie in wait no heat reaches this far into space black mist
rises battle has begun frozen shards rending the sky icy moons ammonia
vapor plumes cryomagma tectonic glacier movement crushing the fortress
wall cold kingdom has been breeched

frost in the wind gathers on the sails

empire will fall when orbits decay all will melt methane seas
will blaze loaded knife cuts like ice sharpened crystal water blade

Eyes into Ashes
===============


staring at the sun until it no longer rises eyes into ashes accept the
light directly into my brain focus the beam on the back of my skull
send it down my spine burn the inverted symbols on the bottom of my

my sleeve lungs on my sleeve eyes into ashes eyes into ashes lungs on
my sleeve eyes into ashes lungs on sleeve ashes lungs on my sleeve

Consorting with Loathsome Beasts
(lyrics based on the poem Throne of Deformity)
===============
Drawn upward, into mountains cold with rain
and forest, into narrow clefts of stone,
upward from convention, cities, pain
of loss--I sought to be alone.
And there in secret caves I found a throne
constructed for a body strangely shaped--
not manlike, not God's making. I escaped.

I wandered then into a valley, green
with life, yet sickly somehow too--
I heard the scrabbling of things unseen
Breathed alien air, saw poison in the dew.
I thought to flee, but yearned to stay there too.
And then the night took hold, and all around
the beast-things came up writhing from the ground.

They were the image of the form I'd seen
Reflected in that throne; not dead
But horridly alive, slime-blackened, lean
with hunger for my aching flesh. I bled
where pale claws scratched me. Tasting me, they led
my witless form back to that mountain cave--
before their empty throne, made me their slave.

And time has flowed, and altered me in flowing:
for as the months or centuries went darkly by,
my torment and delight each moment growing,
My man's form died. But I will never die!
My shape may not be comely to the eye,
You'd see it in the night and know despair--

But now it fits, in every vile detail, that chair.
