A Chaos Sorcerer with a... problem

The situation was agonizing.

The room was black, pitch; not a single source of light to be found and yet you could see perfectly. You sat, naked, on the cool metal floor of your chambers: legs crossed, back straight, hands on your knees, palms up. You could feel the chill, almost damp, air of your quarters press against your skin. Your breathing was slow and measured, every action you took was precisely controlled. And yet, you felt your twin hearts pump, nearly in unison, with such ferocity you could hear them beat. The blood coursing throughout your body: your arms, your legs, your chest. Yet it all seemed to be pooling straight in one place.

Your rock hard, throbbing, erection.

Your bones were stronger than carbon steel and yet you surmised that your engorged member was far more rigid still. The ridiculousness of your predicament was embarrassing. You are Astartes. You do not get erections.

Yet here you had one; and even worse, all of your focus seemed to be placed squarely on it. In all of your many, many years, meditation had never been a problem for you. It was a requirement for any psyker in order to maintain their control and discipline. Those reasons were compounded a million times over within the warp, as its very proximity caused rapid insanity and corruption to even those not attuned to its call.

This knowledge causes a very real concern to cross your mind, 'Have I finally begun to succumb to its taint?' you wonder, and find the implications... disturbing.

Time... time was meaningless in the warp. It did not move steadily forward as it did in the materium. Eons could pass by in an instant, yet, not a stone's throw away, moments could last an eternity. The warp played havoc upon organic and synthetic material alike, instrumentation could not be trusted. It behaved according to its own inherent, unknowable workings. It permitted its use, but brooked no master.

In your time you had encountered uncountable numbers who claimed to hold dominion over it, but they were all invariably insane, or swallowed whole by it. The latter, a display one part irony, one part justice, one part unspeakable horror. The warp was something best left abandoned and avoided, and any sane person did so. But only within a warp storm would the Imperium not look for you.

And you had things to do. Oh, so many things...

Which made your current predicament all the more intolerable. These... inconveniences had been coming, with increasing frequency, over the past several months and not for the first time you wondered 'Why?'.

Meditation had helped in the past, yet had grown increasingly ineffective. As it was, you had been here for, by your count, the last thirteen hours and it had only grown larger. As thick as your wrist and as long as your forearm, yet as sensitive as...

A chime at your door interrupted your train of thought. 'Whoever it is had better bring urgent news.' you think, 'Or I'll have their head for this interruption.'
