The first thing that Natasha Romanoff - as she had allowed herself to be called in recent years - had done after she had popped out of a gooey pod (and subsequently gotten clothed, briefed on the situation at hand, and retrieved her weapons) was familiarize herself with the spaceship that she had found herself on. It had taken a long while - the size of the ship made the SHIELD Helicarrier seem akin to a SmartCar - but she’d scoured as much of the place as she could, because it was always useful to know one’s bearings.

( Especially in a situation like this... )

Outside the Sensorium, a large floating sign proclaimed in large text:

SENSORIUM IN USE. PRIMARY OCCUPANT: AIBGHALIEN MARSAI. PURPOSE: DEPLOYMENT OF SIMULATED AND GENUINE MAGIC. VISITORS WELCOME. CAUTION! NONSIMULATED MAGIC IN USE!

A helpful magic mouth also repeated these words verbally to those who drew close, a necessary sop to potential issues of translation (or literacy). Despite this ungainly addition tio the illusory sign, Aibghalien was pleased with his idea.

Such thoughts had fallen far to the back of his mind, however, as in the Sensorium he had created a fourfold simulated environment. One quadrant, which the door opened onto, consisted of his tower laboratory from his days as a regent, with tables of magical and alchemical apparatuses set up in various states of use or disarray. The next quarter clockwise was a battlefield, with two armies clashing in a seemingly perpetual state of conflict. Continuing around, in the third quadrant, a group of orogs shuffled aimlessly around a dungeon hallway in exactly the manner one would assume orogs would shuffle about while waiting for adventurers to burst in on them in their otherwise empty and joyless 20x20 dungeon room. Finally, in the fourth quadrant stood Aibghalien, dispassionately deploy a mighty gout of fire from his hands into a swarming mass of Kessek.

“Pause,” he said out loud – not necessary, but Aibghalien found it helpful to set deliberate barriers between his general mental thought processes and the commands he intended to give the sensorium. The image froze in the midst of the fire impacting the Kessek armor. Nodding to himself, Aibghalien stepped forward to examine the intersection of attack and defense, analyzing the impact with the intent of improving it.
