I'm A Ramblr

Here are some quotes from the books referencing Warren’s appearance.

'Handsome and quiet? White hair and skin? Dale's brother' Warren was no longer albino. He had dark hair and intense hazel eyes. Warren wore a dark orange T-shirt and gray sweatpants. Contrasted against the shirt, his arms looked white as milk. Dale turned him so that he was seated on the edge of the bed. When Dale let go, Kendra half-expected Warren to topple over, but he remained seated upright, eyes vacant. He looked to be in his twenties, at least ten years younger than Dale. Even with pale skin, white hair, and empty eyes, Warren was unexpectedly handsome. Not quite as tall as his brother, Warren Had broader shoulders and a firmer jaw. His features were more finely sculpted. Looking at Dale, she would not picture his brother handsome. Looking at Warren, she would not picture his brother plain. And yet seen together, a family resemblance persisted. Standing in the doorway, he studied her. He looked even more handsome now that he had possession of himself. His striking eyes were a silvery hazel. Had they been that color before? He ran a white hand through his thick hair, then stared at his palm. "I thought I was looking sort of bleached", he said, flexing his fingers. "I have leather armor under my shirt," Warren said. "The freak still gave me a good scratch. I keep my knives sharp." Warren crouched, recovering his throwing knife from where it had fallen. Warren wore several new rings and clung to a sheathed sword with a pearly hilt.

Seeing that he had "several new rings" implies he would wear rings normally, and that those are additions.

When introducing himself, Warren mentions being a Scorpio, making him... something of a zodiac girlie.

All this gave me the impression of him that you see reflected in his design. The throwing knives, too, and evidence of frequent injury are present.

Below is a design for the sword with the pearly hilt from Lost Mesa. Swords aren't a weapon really seen in Navajo or Hopi cultures, so I tried to make a sword of fairy-like design.
