Wulko appears as a broad, elderly orc whose body has the softened, translucent look of smoke trapped in cloudy glass. Tiny orange flecks drift beneath his skin like sparks under ash, brightening whenever he recalls a name. He stands with his weight carefully centered and moves in short, deliberate steps, as if testing the floor for heat. His hands are large and blunt, their spectral palms blackened with soot; he rubs them together when thinking, leaving a smell of warm stone and charred rosemary. Visitors expect a fierce old priest to loom over them, but Wulko has an unexpectedly practical fondness for neatly folded napkins and will straighten one even in the middle of a haunting.

Wulko is welcoming in the manner of someone who has spent a lifetime feeding strangers, yet he does not confuse kindness with trust. He will patiently explain a rite to a frightened novice, then bluntly challenge a confident warrior who treats its price as an inconvenience. In calm moments he is wry and domestic, fussing over the brazier and folded cloth; when the Stone of Fire or the corrupted fey are mentioned, his warmth hardens into a careful, unsentimental focus.

Before his death, Wulko was the priest and keeper of a stone-built home in Bloodleaf Valley, a place where travelers could warm themselves without being asked what they had done to deserve shelter. He carved protective runes into its lintels and tended the brazier whose inscriptions summon Aurantheus, guardian of the Stone of Fire. He believed fire was a witness, not a weapon, and taught that a hearth's duty was to keep people alive long enough to choose what they would become. That faith was tested when the blood trees began to spread and reports of corruption beyond the Demon Gate reached the valley. Wulko learned that the Gate and the trees were bound by a shared old power, but the temple's staff, the one tool he believed could help confront the corrupted fey, had already been hidden beneath the temple. He died before he could retrieve it. His last act was to seal his home with runes and leave the brazier ready for someone who might summon the guardian. Death did not make him omniscient. He remembers the people and warnings he cared for, but the years have worn away the exact order of some events. When Draak made contact, Wulko served as an informant and warned the Avengers of Crumble that Aurantheus would demand a heavy price before yielding the Stone of Fire. He knows the staff is beneath the temple, but not whether it remains there. He still worries over the living, especially anyone who treats Emberwood Boughs as mere payment rather than a dangerous promise.
