Onward indeed. All that remains is to open a door.
As the conversation concludes, Blastralion's form begins to subtly shift. The core of his body shrinks slightly, the extra mass flowing smoothly to cover vitals, the scintillating exterior forming a shape more reminiscent of armor than flesh. Squat pyramidal spikes form at the knees, elbows, and heel. At the joints, in lieu of a fixed exoskeleton, fine overlapping scales take shape. The transformation is complete in a matter of minutes and does not seem to interfere with talking or listening. The new armor, unconstrained by crafting limits, is smooth and rounded in most places, to deflect blows. Each and every ounce serves a defensive or offensive purpose - or, in some cases, both.
His preparations done, Blastralion leads Lightless to the exit. With a final warning to the necromancer - "things will get very chaotic, very quickly" - he draws his sword and opens the door -
- instantly flooding the room with the screams of the dying and the clamor of battle. Depending on Lightless' experience, he may recognize: human shouts of command, fear, and agony; decidedly inhuman shrieks and howls; the sound of snapping bones; the clang of metal on metal; and a few more esoteric sounds, like that of exposed, hardened bone dragging across a stone floor.
On the other side of the door is a dimly-lit corridor, perhaps two paces wide, stretching to the left and right of the doorway. Blastralion turns right, breaking from a measured walk into a dead sprint with unlikely precision. Towards the end of the corridor, a creature like an extremely muscular, wingless bat is busy mauling what might, at one point, have been an armored man. The bat-thing is hunched over its victim, but could easily be nine feet tall if it cared to rise. Blastralion doesn't give it the chance; he decapitates it with almost casual ease. He then proceeds to carve his way through several smaller aberrations in rapid succession, barely slowing, until he meets another bat-thing as it is climbing through the twisted bars of a ruined portcullis. This one, he tackles bodily, sword-point-first, sending the pair of them back through the twisted metal, one chunk of which rips a bloody gash along the bat-thing's side.
Just like that, the path to the overrun courtyard - and presumably the gatehouse beyond, though Lightless cannot see it from here - is clear of obstacles. Aside from some very fresh corpses, that is.
