Here's from my logs:

look chief
An ancient man is sitting cross-legged on the ground here, the one that the
OneHearts hail as chief and heart of their people. Shrunken and old, his
back is lumped in a prominent hump. His dark eyes were probably clear and
lively once, but are now set deeply into his face, as they try to squint
past his drooping eyelids. His lips are withdrawn as they join to form a
single line on his face and most of his teeth have fallen out, while those
that are still alive are blackened with decay. His skin looks like an
over-sized robe he wears as it sags and wrinkles badly, rubbing against his
bones with every move he makes. Yet his ancientness proclaims his wisdom
clearly to all, as his people entrust their secrets to him boldly, and lean
their ears close to his lips to catch the advice he spills forth in whispers.
The OneHeart chief is in perfect health.

the OneHeart chief is using:
<worn on body> a long buckskin shirt
<worn on face> a gaudy tribal mask
<worn on legs> a pair of long buckskin leggings
<worn on feet> a pair of hard-soled moccasins
<worn about waist> a smoky strip of tanned hide
<mainhand wielded> (Glowing) (Humming) the blessed polearm of wrath

I'm good, he's good, am I missing something? If its an Ethos thing, does that account for the rejection of the weapon?
